I think I have found the burial of Jean (Jeannie) Sheldon in Sheffield in 1919 aged 38.
Looks like she was buried in a communal grave because all the others in the grave are buried roughly the same time.
It says she died at the Union hospital and it states her body was removed from Sheffield Parish to Burngreave but why would they move her from Sheffield Parish for a burial when surely there were places closer to the Union Hospital she could have been buried in.
I can understand her being moved if there was a family grave but the grave she was in doesn't seem to be one.
Going bvack to this tree, trying to fill in more blanks, It looks like William Burgess Sheldon had two siblings Lilian Alice born 1905 Southampton and Ivy A born 1904 in Egypt.
I have found the girls living with their grandmother Julia Alice E Sheldon, nee Griffin on the 1911 census.
I am trying to find William born 1877 and Jeanie born 1881 on the 1911 census to see if that tells me how many children they had etc but as not yet I have had no luck. Presume they might have been back in Egypt.
Also if anyone has Ancestry, are the hampshire marriage certs on line and if so could they look at the marriage for william C E sheldon and Jeanie Buchanan and tell me the name of her father please.
