Hi Monica,
Going back to the drawing board and taking into account the definates (having been round the world and back and knowing everything about every Alexander Williams lol).
My Alexander Williams married Catherine Rafferty //at North Shields Registry Office 17/05/1913 He is 44 years Bachelor occ Engineering Labourer - father named as John Williams Deceased, Mariner.
I have a birth of their first daughter Winifred C Williams Sept 1913-1931, I presume the reason they married at the registry office is because she was pregnant with Winifred at the time.
Having looked at the 1901 and 1911 census, there is an Alexander Williams b 1869 living as a boarder in South Shields and his occupation is Engineering shop labourer born Banff. I have a hunch that this is my Alexander Williams as it would be very unusual for two people with the same name living in the same area with the same occupation and age living in South Shields and coming from Banff.
The problem there starts............. I cannot find an Alexander Williams born in Banff in 1969, I have found others, but not for the exact year which means I am unable to get hold of his birth certificate.
Another hunch I have is that Alexander was living with Elizabeth on 1901 census and they had a child called Alexander b1901, I dont think they were actually married, I think maybe she took his surname. I cant find a death for either Elizabeth or Alexander Jnr, which makes me think that the couple separated and Alexander Jnr was brough up by a stepfather with his mother remarrying. This may be totally wrong, this is something I need to explore a little further. I feel that Alexander may not have told Catherine that he already had a son called Alexander, the information I get from my family is very vague as he passed away when my mother was young, however, it has been mentioned that he was a very closed person and his motto was "tell nobody nowt"!
Can of Worm!!!!!!!!!!!!!!!!!!!!
