Hi Peter,
Sorry for delay in replying, apart from being away for a few days, I couldn't find your reply, I'm probaby being a little dim here as I only managed to find it through 'search'. I haven't got the hang of this site yet.
Re William & Mary Ellams: As you said, on 1841 census it shows Joseph 1837. He is the son of Ellen Ellams (dau. of William & Mary). He was born illigitimately. Ellen b. 1817 married 8 years later to John Lockett.
Mary Ellams b.1837 also mentioned on same census is a mystery so far, I can't find anything on her.
I have a copy of William's Will which mentions Mary, his wife. Also a daughter named Mary, but surely it couldn't be Mary 1837 as that would mean wife, Mary, was 55 when pregnant.
I haven't managed to find a William Ellams of Runcorn.
I would dearly love to find siblings of William but no-can-do without his birth or marriage certs. Is there any way you can help please?
Jill.
