Hi Millie, Never the expert but this is what I have;
Margaret born 1825
to John and Lucy Quay.
William Born 1826 to John and Lucy Quay.
John and Lucy married 1829
1851 Census Margaret Christian?
and William Kewley visiting the Quays.
3 Wks later Wm Kewley and Margaret Craine are married.
1871 Census Wm Kewley is Head of the family and Lucy Quay is Mother in Law,
I've re-read the posts and I too am confused as to what happened to Will Quay!
If Margaret is Lucy's daughter then she would be the sister of Manasseh who is my G. Grandad.
It's been a while since I have worked on the family history and since reading your posts I've been bitten by the bug yet again! Frances has certainly got me thinking so it's back to the drawing board for me.
Happy hunting - Mary ...............
