Thank you Anne, your right something isn't right, I have tried for a couple of years now and researched every Williams in Banff to the extent of anyone in Scotland
Monica, I would love to know what happened to Elizabeth because I cant locate a marriage for him to Elizabeth and then cant find a child Alexandra born in 1900, I am familiar with Northumberland/Durham but that hasn't helped, I am swayed to believe that they weren't married and like Anne mentioned about his birth "Something isn't right".
I definitely know he married in Northumberland in 1913 as a Bachelor (to my ggm), with a father named as John (deceased) but that hasn't helped either.
I think he moved from his birth town in about 1880's and ended up in Durham. I have for definite on 1901 (birthplace Banff) and 1911 (birthplace Banff, Scotland) census and both so that's why i questions where it could have been exactly. It does seem strange that he would have moved to Durham from Banff unless of course he was involved in the Fishing Industry.
Then I question why would someone say they were born in Banff, why Banff, how would he have even heard of a town called Banff if he didn't have a connection with the Town.
Researching your family history should come with a warning about how frustrating it would be.
