Hi Sam
Thanks for the offer but I wouldn't want you to spend a lot of time looking for them. The first child I know of, Edmond, was born according to the 1851 census about 1830 in Liverpool. It's possible there are older children but I don't have details of the 1841 census. Perhaps I should be patient and wait until I can get access to the 1841 census or the parish records.
Cheers Genna
