Hello, I recently got some new information on this line of my family so have taken it up again and found your post.
Henry John Smith and Louisa Anne Hobbs are my GGG Grandparents
My grandma says she used to call their son "Jagger Bull" instead of grandad. She says his father was a pianist and mother was an opera singer but took to the drink and the children got taken away and put in Bernados. Apparently he went on to become a rag and bone man then a sailor then worked on the docks. (I'm not sure whether this story is in the right generation) If you can shed light on this that would be great. Didn't know about a drowning in the thames so will investigate.
