I'm trying to track down William Caswell, who married a Margaret Nesbitt/Nisbet probably in Ireland after 1840 before 1868. They had, to my knowledge, two children: James Carswell born in Newtown Hamilton, Armagh, Ireland on 10th March 1871 and a daughter born 5th October 1868 in Newtown Hamilton Armagh, they moved to Scotland sometime after that and James married a Mary Walker, and they lived at McCulloch's Land in New Stevenson, Scotland, they married on 13th August 1897 and both parents were present. They went on to have George Walker Carswell (the name had changed by then), 14th May 1910, he married on 25th December 1935 to a Mary Campbell Pinkerton, and the rest of the family are still living. I have many blanks but deparately want to find out about William Caswell/Carswell or Margaret Nesbitt/Nisbet his wife.

Can anybody help?
