Clara Louisa Chatfield dies June qtr 1896 aged 5 months
Baptisms only for Harold and Clara Louisa ( possibly it was thought they would not live that long:-
Harold Chatfield 29th March 1893 Newington Father Frank occ Fisherman Mother Sophia address 76, Paisley Street
Clara Louisa Chatfield born 27th December 1895 baptism 15th January 1896 Hull, St Matthew Father Frank occ Fisherman Mother Sophia Louisa address 76, Paisley Street
The only thing that would concern me regarding the possibility that Frank is the son of Henry/Frances is that the first born male child was a George Frank, George being the father of Sophia, Frank/Francis that of Frank?
None of the children contain the name of either of the parents/ siblings of the Frank born 1859 Cheam in 1861 census.
