My g.grandfather Charles Mortimer gives his date of birth in the family bible as 5th February 1855, though this replaces an earlier crossed through date of 1854. In the early census returns he gives his place of birth as Ipswich, though this is later replaced with "Bow" then part of Poplar.On his 1875 marriage certificate he gives his father as Charles Mortimer(dec'd) In the later 1891 census he adds the middle name of "Chaston" Family oral tradition has it that he visited Somerset House and established his parental line and the fact that he had a brother, but my enquiries of Tower Hamlets , the current Registration area which includes the old parish of Bow have drawn a blank. Any suggestions and help gratefully received. Many thanks Roger M Evans
