I have been trying to pin point the exact Charles. He died on 15 April 1918, it states that he was 35 years old and born in Sittingbourne- although Sittingbourne was not a registration centre s0 could have been Faversham or Milton. The only census record that has a Charles born in Sittingbourne is the 1891 census which states that his father George is a brickmaker and Charles is 9 years old. By the 1901 Census this George's wife Emma is a widow living in Gravesend - which doesn't make sense that he is not mentioned as 'son of the late George Baker'.
The other confusing information is that Charles is with the South Wales Borderers, although he originally joined 29th London Regiment, he enlisted in Canning Town but resided in Clacton-on Sea.
As you can see this one is a little mixed up!!
