Others have sought distinguish between various Hamitons named John. Whether managers/curators think there's reason/value in making a suffix change to this profile, I don't know as I note the following.
John Hamilton of Broomhill 's profile name has exactly the same suffix as his son, John Hamilton of Broomhill . Stirnet gives this John Hamilton a different suffix:
— "John Hamilton, 1st of Broomhill (a 1473, d 08.1526)"
However, Burke, refers to another John Hamilton as "1st of Broomhill". — http://google.com/books/edition/Genealogical_and_Heraldic_Dictionar...
Stirnet doesn't give a reason for showing "1st of Broomhill" for its John Hamilton, and neither did Burke for its designated "1st of Broomhill" . Apparenty, both authors sought to differentiate two different John Hamiltons from from their sons. Stirnet's author(s) further says it's fruitless to grapple further with Hamilton genealogy at this juncture giving this conclusion:—
"There are disagreements between our sources on the early generations of this family. There was even major disagreement 'within' a source as Anderson's 1827 Supplement to his 'Memoirs of the House of Hamilton' made significant revisions to the account of the family he had given in the original 1825 Memoirs. The 2015 revision of this page was made before we had access to 'Hamilton History' (1933) but gave some precedence to Birnie's 1838 work which appeared reasonably reliable. That view was supported when the page was revised in June 2016 with the benefit of 'Hamilton History'. Not least because that book is the most recent of the major potentially-useful sources that we know about and may reasonably be viewed as now The Definitive Work on the Hamiltons, the following follows 'Hamilton History' but we have kept note of much of what the others sources show in order to explain why we may differ from what various other web sites show on these generations.
