Hi
New to this, but came across your questions while trying to find out info myself on James Townsend.
I have the following on him;
Born abt 1823 Bromley Kent
1851 a footman for the Marquess of Camden at Wilderness Park, Kent
1860 he marries Catherine Salter Leare of Chudleigh, Devon in London but I cant find him in any of the census for 1861. Catherine is back home with her parents.
1871 and 1881 he is at 6 Upper Belgrave Street working as a butler for Robert Pulsford.
He retires and go to live with Catherine and their many children in Devon to run the Plymouth Inn in Chudleigh. I still have them both alive and in Chudleigh in 1901, he is 78 and she 68. There oldest daughter and their son-in-law are now running the pub. Catherine dies in 1907 in Richmond, Surrey which seems odd, so perhaps it isn't her although dates and name match and cant think there are that may Catherine Salter Townsend's, and London has played a big part in their lives.
I dont have a death cert for James.
The family myth is that Catherine and James met in London while she was visiting with her parents. She either became pregnant by him or he was persuaded to marry her because she was in trouble by another. Don't imagine we will ever know the truth!
