I made some progress on my own Galts over the weekend.
My gggg grandmother Margaret Galt married John Ferguson. She died in 1869 and in her will she mentions her sister Mary Price and brother James Galt.
Mary Price (née Galt) died in 1874 and she also mentions their brother, but names him as “James Galt of Clareview, Ballyclare.”
James Galt married Mrs Martha Saunderson (née Mahood) in 1858:
[Northern Whig, 7 Jun 1858]
GAULT-SAUNDERSON: June 3, at the Presbyterian Church, Carrickfergus, by the Rev. Robert McCully, James Gault, Esq., Airview, Ballyclare, to Mrs. Saunderson, Ballyclare.
They had at least four daughters, the last of whom made it into the civil registrations. Margaret Galt was born on the 30th Jan 1866 (parents Galt and Mahood) and died in 1867:
[BMN 8 May 1867]
April 27, at Clareview, Ballyclare, Maggie, fourth daughter of Mr. James Gault, aged 15 months.
This confirms that James Galt of Clareview is the same person as James Gault of Airview. And going back to his marriage cert, James’ father was also called James. So I now have:
James Galt m? and had issue:
1. Margaret Galt (1 Mar 1801 – 18 Dec 1869) m. John Ferguson
2. Mary Galt (c1812 – 10 Mar 1874) m. Hugh Price
3. James Galt (c1821 – 10 Mar 1905) m. Martha Saunderson/Mahood
Plenty of room for other siblings.
The will of James Galt who died in 1905 leaves provision for a headstone to be erected over his grave in Kilbride. Unfortunately (going by the discovereverafter website) it looks like there is no headstone there now, if there ever was one. However, the plot is right next to the other Galt/Gault graves beside the mausoleum, including Alexander Galt (c1805-1883) who married Ellen Murdoch.
