William provides the earliest documented personal association between the Guthrie name and Innerlownan or Lownan. Later Arbroath records name Robert, James, John, and Hercules Guthrie as tenants of the same property, suggesting a continuing Guthrie presence there. The records do not prove that these later tenants descended from William.

Strongly supported: The William recorded in 1418, 1434, and 1438 was one individual.

Probable: William Guthre of Lownan in 1450 was the same man.

Possible: Walter Guthre of Lownan was a relative, and the unnamed wife recorded in 1437 belonged to this William.

Unconfirmed: William’s parentage, children, connection to the later Lunan tenants, or relationship to the Kincaldrum and Guthrie of that Ilk family.

The William of Guthre who served as alderman of Forfar in 1464 should remain a separate identity unless further evidence connects them.

Documented: James Guthrie was the brother of Sir David Guthrie of Kincaldrum.

Because David was identified as the eldest son of Alexander Guthrie and Marjory, James’s stated brotherhood strongly supports placing him as another—and probably younger—son of Alexander. The records reviewed do not establish whether Marjory was also James’s mother.

Strongly supported: The custumar of 1472–1476 was the James who witnessed the 1476 instrument and later served as bailie and juror.

Probable: The appearances from 1457 through 1483 describe one man whose career developed within the financial, legal, and civic administration of Arbroath.

Compiled genealogies associate Sir David’s brother with Halkerton, but no contemporary record reviewed here styles him James Guthrie of Halkerton. That territorial identification remains unconfirmed.

James must remain separate from later Arbroath men of the same name, including James the elder, husband of Katherine Lyn; their son James; and the James Guthrie associated with Janet Panter and Mylhill.

Documented: John Guthyn was a priest belonging to the Diocese of St Andrews and a public notary authorized by imperial authority. His work in 1469 extended from Aberdeen’s sheriff court to Abbey property in the barony of Tarves.

John’s diocesan affiliation does not establish that he was born or resident in St Andrews. Nor do the records identify him as a monk or permanent official of Arbroath Abbey. He appears to have served as a professional clerical notary employed in the Abbey’s legal affairs.

The Aberdeen transumpt incorporated the 1457 instrument naming Sir David Guthrie of Kincaldrum and his brother James. John therefore authenticated a document involving two contemporary Guthries, but this was a professional and documentary connection. It provides no evidence that he was their relative or belonged to the Kincaldrum family.

John should also remain separate from the contemporary John Guthery of Eassie. Although the chronology permits comparison, John of Eassie appears in territorial and landed contexts, while John Guthyn is identified only as a priest and notary. No record currently connects those identities.

John’s parentage, birthplace, benefice, residence, and relationship to other Guthrie families remain unresolved. Further identification will most likely come from another instrument bearing his full notarial subscription or notarial sign.

Documented: William Guthrie held Kinblethmont by 1470 and served as a juror in the Forglen inquest in 1494.

Strongly supported: He was the William of Kinbrachmont who had formerly acted as Walter Fullarton’s guardian and successfully accounted for that administration in 1479.

Documented: Alexander Guthrie of Kinblethmont was William’s son and heir. Alexander later appears with his wife, Janet Strachan, in the Arbroath records of 1526 and as one of the Abbot’s special bailies in 1527.

The documented succession begins:

William Guthrie of Kinblethmont
→ Alexander Guthrie of Kinblethmont
→ Thomas Guthrie of Kinblethmont
→ William and Robert Guthrie of Kinblethmont

Possible: William’s wife was Dovay Leslie, a reported daughter of Sir William Leslie. The Leslie tradition instead describes her husband as Thomas Guthrie of Kinblethmont, while later reconstructions transfer her to William’s generation. The proposed correction is plausible but is not established as clearly as the documented father–son relationship between William and Alexander.

Possible: William was the same man as William Guthrie, Alderman of Forfar, active from 1464 to 1466. Their chronology, locality, civic standing, and administrative experience are compatible, but no record directly connects the alderman with Kinblethmont. They should remain separate working identities.

Possible: William was a son of Alexander Guthrie, 1st of Kincaldrum, and therefore a brother of Sir David and James Guthrie. His generation, territorial status, Angus associations, and later connection with Kincaldrum permit this placement, but no contemporary record reviewed identifies his father or calls him a brother of Sir David.

The traditional identification of William as of Eassie also remains unconfirmed. Kinblethmont is his only securely documented territorial designation.

Documented: Master Malcolm Guthrie held the preceding tack of the Abbey lands of Guthyn and Wester Brex before Pentecost 1496.

Documented: A Master Malcolm Guthrie acted as Sir Alexander Guthrie’s legal procurator in 1501.

Strongly supported: The Abbey tenant and the procurator were the same individual.

A particularly significant candidate for his fuller identity is Malcolm Guthrie of Balnabreich. On 4 February 1472, Sir David Guthrie of That Ilk granted Balnabreich to Malcolm Guthrie, expressly identified as his natural son.

If Master Malcolm was the Balnabreich grantee, his documented position would be:

Sir David Guthrie of That Ilk
→ Malcolm Guthrie of Balnabreich, natural son

Under that identification, Malcolm would have been the paternal half-brother of Sir Alexander Guthrie. His appearance as Sir Alexander’s procurator in 1501 would then represent one brother managing legal business for another.

The reconstruction is coherent in chronology, geography, social position, and family association. Malcolm’s learned title and legal role would also explain why Sir Alexander entrusted him with representation before the Lords of Council.

It remains unproven, however. No record reviewed calls the Abbey tenant or procurator of Balnabreich, and the 1472 charter does not style Sir David’s natural son Master. A procurator was not required to be a relative, so Malcolm’s service for Sir Alexander cannot by itself prove a brotherly relationship.

Strong possibility: Master Malcolm was Malcolm Guthrie of Balnabreich, natural son of Sir David Guthrie.

Possible familial interpretation: If the identification is correct, Malcolm was Sir Alexander’s paternal half-brother.

Ruled out: Master Malcolm was not Malcolm Guthrie of Kingennie. The Kingennie man died on 24 November 1482 and was already described as deceased by 1484, well before the appearances of 1496 and 1501.

Malcolm’s parentage therefore remains unresolved unless his identification with the Balnabreich grantee can be confirmed. His degree, precise profession, marriage, children, and date of death are also unknown. If the 1496 and 1501 records concern one man, he was alive on 10 May 1501.

Documented: Marjorie Guthrie was the wife of Charles Brown, burgess of Arbroath, on 14 November 1505.

Documented: Marjorie was named with Charles among the principal spiritual beneficiaries of his perpetual chaplainry at the altar of St Nicholas.

Strongly indicated: Guthrie was Marjorie’s own family name. Because her husband was surnamed Brown, she was not merely a woman who had acquired the Guthrie name through this marriage.

Documented: Charles possessed sufficient property and annual income to establish and support a perpetual chaplainry, placing the couple among Arbroath’s prosperous burgess community.

Documented: Charles Brown was married to Margaret Ochterlony by 18 April 1513.

Probable but not documented: Marjorie died between 1505 and 1513. Charles’s later marriage establishes that their marriage had ended, but no record reviewed explicitly records Marjorie’s death.

Possible: The neighboring James Guthrie was Marjorie’s father, brother, or another relative. Shared surname and adjoining property make the relationship worth investigating, but the evidence is geographical rather than genealogical.

Possible: Marjorie belonged to the family of Sir Alexander Guthrie of That Ilk or one of its collateral branches. The charter does not identify her as Sir Alexander’s daughter, sister, niece, or cousin.

Not established: Any part of Charles’s property portfolio came through Marjorie as inheritance or marriage property.

Not established: Charles and Marjorie had children. The charter’s reference to “successors” does not prove direct descendants.

Marjorie should remain separate from the earlier Marjorie, wife and widow of Alexander Guthrie, 1st of Kincaldrum. That woman’s birth surname is unknown, while Charles Brown’s wife was explicitly named Marjorie Guthrie. She should also remain separate from the unidentified Lady of Guthrie who held property in Arbroath in 1483.

Marjorie’s parentage, territorial branch, children, and date of death remain unresolved.

Documented: John Guthrie was the father of Hercules Guthrie.

Documented: John and Hercules jointly received a nineteen-year tack of Innerlownan and its garbal teinds on 28 March 1526.

Documented: Their obligations included substantial grain rents, riding with the Abbot, transporting tiles, and attending the regality courts.

Strongly supported: John and Hercules belonged to the established Guthrie tenancy family associated with Innerlownan since at least the fifteenth century.

Probable: The Hercules named in 1526 was the later Hercules Guthrie of Lownane and Over-Dysart, whose testament was recorded in 1565.

Probable if that identification is correct: Hercules married Jonet Anderson, who was identified as his widow in 1582–83.

Possible: John succeeded James Guthrie through inheritance or family assignment. Their exact relationship is not stated.

Possible but unproven: John was the eldest son of Henry Guthrie and Elizabeth Lyell and later became John Guthrie, 1st of Colliston.

Possible: John or Hercules was closely related to Margaret Guthrie, wife of Sir Robert Carnegie, who was traditionally described as a daughter of Guthrie of Lunan. The 1526 tack does not identify her father or connect her directly with either tenant.

Unresolved: John’s parentage, wife, date of death, and relationship to the earlier Innerlownan tenants.

Unresolved: Hercules’s mother, children, precise rights in Over-Dysart, and date of death.

The secure pedigree supplied by the Arbroath Register is therefore:

John Guthrie, tenant of Innerlownan
→ Hercules Guthrie, probably later of Lownane and Over-Dysart

Documented: Alexander Guthrie was territorially styled “of Grandon” in 1535.

Documented: He was the father of another Alexander Guthrie, explicitly described as his firstborn son.

Documented: Father and son jointly received a nineteen-year tack of Mondornach.

Documented: Mondornach lay within the sheriffdom of Aberdeen and the barony of Fyvie.

Documented: The tack included permission to construct a mill for the tenants’ profit and the rights of wrack and wair.

Strongly supported: The younger Alexander was included to provide generational continuity within the tenancy.

Possible: Grandon was a historical form of Grandhome or Grandholm.

Possible: The two Alexanders represented an established northeastern Guthrie branch.

Not established: The elder Alexander was the hereditary proprietor or laird of Grandon.

Not established: Either man was identical with Alexander Guthrie of Kinblethmont or an Alexander of the principal Angus family.

Unresolved: The elder Alexander’s wife, parents, siblings, and date of death.

Unresolved: The younger Alexander’s mother, age, marriage, descendants, and later succession.

The secure pedigree presently extends only through these two generations:

Alexander Guthrie of Grandon
→ Alexander Guthrie, his firstborn son
