I am sorry the lack of information but I don't have a lot to go on except the 1891 Census the mention of Kinaldie was in the letter he wrote to home I'm guessing its near Aberdeenshire?

[
[George Sinclair says he was from Aberdeenshire] I thought that bit of info may help
I finally had a bit of luck last night and found Betsy maiden name was Cobban Now I need to locate George and Dave Smith [4yo] If George was 31 then he must have been born in 1860 [a guess] and maybe married in the 1880's [another guess]
Im struggling with the info I have as Its so limited.... that is why i asked for help.... i see my first post was lacking..... sorry I am only learning..... been told less is more..... so i kept it short.... but way to short if anyone can help me or point me in the correct direction thankyou if not that is fine also
