William McNab was born in Stranraer Wigtownshire in c1826. (according to 1851 census)
Cant' find him in 1841.
In 1851 he was married to Ann McDonald living in Middle Greenock.
In 1861 he was living in Rickergate Carlisle with 3 children.
In 1871 I can't find him, she is living in Glasgow with just one son, living under her maiden name, her son was William McNab plasterer. No idea where the, by then, 4 girls were, the youngest 2 were born in northern England.
1881 Ann McNab widow was living in Govan Glasgow with 4 girls.
In 1891 she was living in Dundee.
So pinning their locations down is tricky.
Death certificate says Journeyman Plasterer, married to (blank), Married, aged 50 the informant/Witness I have attached. I haven't followed through on this person. But I think it says his employer who lived in Glasgow.
