Absolutly driving me insane!!!!
I did come up with this though from 1861
Mason 1856 Grandson Hammersmith St Peter Middlesex
Mary Ann Mason 1792 Sundbury, Middlesex, England Head Hammersmith St Peter Middlesex
when I looked at image it did say that mason is a grand daughter and not a grand son and the first name is missing??
I have no idea of her mothers name or any siblings there I am sorry emily.
- but Keziah's first child was named Caroline Mary - not sure if this could be a clue or not

Thanks everyone
Love Jan xx
