Trying to find additional information on John and Elizabeth Blackwell. According to 1871 Census John was born in Bradwell, Buckinghamshire in 1803 (age 66). In 1860 he was living in London and working as a Coachman. His daughter Harriett Blackwell (my grand grandmother) was married at old St Pancras Church in 1860. At the wedding there was a Richard Charles Blackwell. In 1871 he and Elizabeth are living on an annuity in London. Elizabeth was born in Suffolk, England and was 60 years old in 1871 (born 1809). I can not find them in the 1881 Census and assume they had passed away by then. I would like to find information on (1) John's mother, father, and siblings (2)marriage place and date (3)Elizabeth's maiden name and (4) when he migrated to London and (5) who was Richard Charles Blackwell, a brother or son or other relationship. Any information or suggestions to finding data would be appreciated. Brian Sealy
