Here's a follow up on some information I found regarding James Thoms. First there is a correction on his birthdate to May 29, 1867, this would make his age noted on census as being closer to his actual age. I found him in 1891 still living at home with his mother, Elisabeth, Johann and Margaret, there was no mention of the father so I'm assuming he passed on. I also found another sibling while looking for more information regarding Johann. Seems there was an older sister, Joan Bisset Thoms b. June 23, 1859, as yet I can't find anything else about her. As far as James getting married I did find one that the time period fits but not sure without actual records to verify whether he is the right James. There was a James Thoms m. 1892 Dundee to Jane Moore McRae (sometimes spelled McCrae). I found 2 children Elizabeth b. 1894 and Jemima b. 1896. Does any of that tie in with your family? I'm trying to find a 1901 census that might be able to clear some things up. I'll keep looking and get back to you.
