I'm trying to locate the death of William Thomson. He was born on 21 February 1858 in Jedburgh, Scotland and is the son of Thomas Thomson and Ann Nisbet. He married Agnes Richardson 17 May 1883 in Hawick, Scotland. Agnes died in 1894. I have found two children from the marriage, Annie (b.1884) and Thomas (b. 1888). My great aunt is convinced there were other children from William and Ann but I have not been able to locate.
She also says that Thomas remarried and had another son, again and I struggling to locate any detail on this.
Any help would be very much appreciated.
