Hi again
I noticed the David Cadman, nephew, 18, on Pam's 1861 listing.
This is , I think, is the family
1851
16 Cannon Street,
HO107/2019/567/23
Cadman
David, 41, coal miner, b. Staffs, Bilston
Louisa, 40
Mary, 11
David, 8,
Catherine, 6
Steven, 2
John Lewis, lodger, 22, stone miner
All but David senior b. Wolverhampton
David, snr, also shown as b. Staffordshire in 1841 HO107/999/13/30/23
Louisa's maiden name appears to be Bate.
Also, with William and Mary on the 1841 HO107/999/12/15/22 is a 19 year old Mary Cadman born Staffordshire. She might possibly be a sister or close relative of William.
I wonder if the family moved between Staffs and Scotland. it might be worth trying to trace David and Mary in Staffordshire to maybe find their parents.
