I've attempted for years to verify the info on David's Scottish roots, and I can find no evidence that David was from Westburn or was the son of Andrew and brother of Gabriel. The only sources I've found are books written in America, all of which seem to use the same info contained in "The Hamiltons of Waterboro". Source material I've found on Andrew of Westburn list Gabriel and perhaps a John as sons. There is no mention of a David. Does anyone have any links to share that show David's Scottish connections?
