It looks like you have got about as far as me with the Joshua Pearl Eleanor Hodgson part of the tree...
I am a decendant of their son Henry, as you are I believe as I think I saw your name on the Kinghorn page!
I know they were married 10 January 1808, St. Leonards Shoreditch, London.
I also have a list of children (which I am too tired to stick up now!) but can pass on. I am hoping to go to Queensland (Australia) in March and get together with an Aunt who has done a great deal of family research, although I am not sure on which branches she has focussed on.
Looking forward to hearing from you, Regards, Michelle Indikt
