I am not confident that this William Graham born circa 1648 in Canonbie and died 1751 in Bullpasture, Virginia was the son of John Graham, Earl of Kincardine who died in battle at the age of 15 in 1645 and have not found any credible records that connect the two as father and son. It is my understanding that John Graham, Earl of Kincardine was unmarried and died childless. I view this connection as an inaccurate attempt to connect this William Graham to James Graham 1st Marquess of Montrose and without credible evidence I would like to see the connection removed until supporting documentation is presented.
