Hi
I've only just noticed this thread and I'm not sure if you've got any further with this family but in 1851 they are in Cefn
HO107-2503-157-10
John Parry, hd, 39,mason*, b. Ruabon
Eliza, w, 29, b. Bilston
Elizabeth, d, 4, b. Bilston
Mary Ann, d, 2, b. Bilston
* entered as meason
There's not a good match for a baptism of John in Ruabon. Maybe the family were non-conformist (if so WRJones might be able to help).
The nearest I have at St Mary's are
22 Nov 1814 - son of William (wheelwright) and Ann of Newbridge
28 Oct 1808 - son of Richard and Elizabeth of Cefn Mawr
18 Apr 1808 - son of Edward and Mary of Morton Above
My records for marriages finish in 1837 so I can't help there but Paul might be able to find something.
