Another James Adair to add to the list. Book "A History of the Port of Dublin" by Henry A. Gilligan. pages 16 and 247. "In 1708 the Ballast Office ordered lighters from shipbuilders James Adair, Nathaniel Dyer and Francis Drake".
Lighters were sometimes taken on whaling vessels and lowered down when near a whale.However, they may have been used elsewhere perhaps for unloading ships etc.
Did this James Adair associate with Mr. Hawkins in Dublin ? Was this James Adair a relative of "Robin Adair" ?
