I’m really stuck on this one so any help would be very, very much appreciated
I have a Mark William Gillam in my tree (b. 21-Aug-1855, Shoreditch, Middx, surname recorded as Gillam & mother’s maiden name as Townsend).
His baptism record from 23–Sep-1855 (this time his surname is spelt Gilham) shows his mother’s given name as Elizabeth & his father as Benjamin (occ: Sawyer).
The 3 of them are on the 1861 census living in Bishopsgate, London. Mark is aged 5.
Benjamin Gilliam’s parents were John Gillam (occ: also a Sawyer) and Hannah (maiden name unknown). John & Hannah were both born in Gloucestershire.
Now comes my problem….
I’ve also found a 1861 census for a John (occ: Sawyer) & Hannah Gilham living in Fulton, Gloucestershire. Both were born in Gloucestershire, living with their grandson Mark Gilham, aged 5 and born in London.
The issue is establishing which one of the records is the one for Mark in my tree. I can kind of understand 2 separate entries if the locations were within a few miles (if say one census return was completed in the morning and the other in the evening), but the first record is from London and the second from Gloucester. Surely travelling logistics in 1861 would make it practically impossible for the 2 Mark’s to be the same person?
