re: IGI same film as John Adair bc1660, and Robert Adair, St. Andrew, Dublin, there was :
William Adair 1674 Offaly, (Kings Co.) Leinster, Ireland Film 2034399 ................ Perhaps he was of the "Bellgrove" lineage : William Adair m. 4 Oct 1699, Tiscaran (Moystown Demesne ?), Parish Garrycastle (?), Offaly (Kings County), Ireland to Mary Lestrange / L'strange.Wm Adair dc.1712. If he was also of Dublin, Ireland, was he father of "Robin Adair" ?
