Thanks Trish, I am now thinking Mary & John are the right ones, or they seem to fit the picture, I didn't notice the same address on the census 1871 & 1891, probably was going cross eyed by that stage, so they had in total 7 children, Emily, Anne, Annie, Flora, William, Mary & George, seems like the older girls left or married by 1891
there's no middle name for George in the census, though that could be an oversight
I'll do some more checking but it's looking more hopefull now
regards,
James
( I might get a birth certificate for George )
