Hello,
My Margaret (jean) Wilson doesnt turn up in Inchgreen Street until she is married.
She was born in northern Ireland in 1920. Her parents were Archibald Wilson (b. 1889 port glasgow) and Dora (m.s. Boyle).
The family moved back and forth (assume Dora was from NI) but they had another daughter while in Greenock called Margaret (Jane) Wilson after 1920 and stayed in Port Glasgow.
It's confusing that they used the same first names for both daughters, but this is verified as I am in touch with Margaret Jane Wilson's son. They were known as jeanie and Jane.
Anyway, my Margaret Jean doesn't show up at Inchgreen Steet until she is married as Margaret Jean Nicholl.
14 Inchgreen Street:
Margaret jean Wilson's husband George Nicholl was born at 14 Inchgreen St in 1918 and his parents were George Nicholl and Elizabeth.
By 1945 George and his parents (george & elizabeth) were at 10 Inchgreen Street, he married Margaret Jean Wilson and she moved in with them to 10 Inchgreen Street.
this is Margaret's second marriage by then, her first marriage to a Mr Moulson ended due to his death while in war service).
So, in 1952 when your Martha Wilson died at 14 inchgreen street my Margaret jean Wilson definitely wasn't there but if we could find out who else lived at that address in 1952 we might be able to connect our Wilson's. It is a pretty common name though.
Not sure if this will help make any Wilson connection: There is a James Wilson in my tree b.1821 married to Helen Nairn. I do know that my Wilson line originated in Irvine, Ayrshire and moved to Port Glasgow with industrialisation. They were stone masons and masons. There are many Wilson headstones in the churchyard at Irvine and they worked on the Greenock town hall. Does this link to anything you know of your Wilson line?
