Lady Margaret Stewart born in Stirling, Scotland 19 May 1450. She died 1512 Cherry Burton Yorkshire, England. She had been married three times:
James Hamilton, 6th Laird of Cadzow Hamilton 1415-1479
William Crichton, 3rd Lord Crichton 1455-1493
Sir William John Wade, 1455-1490
Her father was nicknamed Fiery Face and he was born in Holyrood, Midlothian Scotland. He died during the seige of Broxburgh Castle
Her mother was from the Netherlands. Mary (Maria) Guelders Van Egmond. Born in 1430, Noord-Brabent, Netherlands. Died 1463, Roxboroughshire, Scotland. This is all I know and have no 'hard' sources to go with it just a family tradition saying we are related some how to the Stewarts through Margarets marriage to William John Wade via their son John William Wade.
