James second marriage was to Janet Mill and luckily it was in 1855. This says he was the son of George Watt and Mary Munn and he had from his previous marriage 5 children living and 4 deceased
I have James' death certificate in 1868 informant was his son John and have Janet's death certificate in 1872 informant was a nurse
So what I really want to find out is
1. When and where did Elizabeth the first wife die?
2. When and where were the other 4 children born?
3. Are the four missing children the four who were dead on the marriage certificate?
4. Where is Marion on the 1841 census and after the 1851?
5. Where is James Junior after 1841?
6. Where is Mary after 1841?
7. There's an Ancestry tree that suggests Elizabeth married James Thomas Reid in 1857 and I've found census that seem to match but where is she in 1851?
8. I've found John in 1841, 1861 through to 1891 and have his 1892 death certificate but where is he in 1851?
9. Where is Janet on the 1871?
Any help would be really appreciated
