Hi. the Gaults have been in Ulster a long time. From my own family history:-
"The Rev John Grahams 'Derriana' published in 1823 describes a statement from citizens of Coleraine
dated 3rd Feb 1690 which commends the behaviour of Michelburns regiment in the town. Amongst the
signatories are Hugh #1 Bankhead. James Ousteau and John G ........ (illegible)."
and from the Minutes of the Ulster Synod
"On Sept 30th 1691 Hugh #1 Bankhead is recorded as a commissioner from Coleraine together with James
Ousteau and John Gault."
This Hugh's son, another Hugh, married an Elizabeth Gault (Will of Hugh senior dated 4/3/1718)
The same will records Elizabeth Hayland, 2nd wife of Robert Gault of Edindarroc. (Benham's abstracts)
The Bankhead's and Gaults inter-married regularly in Ayrshire before coming to Ulster but I have found no repeat performance in Ulster. I grew up in Banbridge, Co Down and actually went to school with a Linda Gault there in the 1960s
Regards
Matt
