Henry Joseph Sheargold married Frances Ann Restall on 17 May 1798 in Fulham. I am 99% sure that he was a solicitor.
I didn't know about the marriages of Frances Mary and Sarah - thanks for that information. Are you descended from one of these?
Francis Benjamin (a tailor) married Mary Ann Bland on 5 July 1827. They had children Louisa (c1829), Henry (c1830), Frank (c1832), George (c1835) and Christopher (c1839). I have christening and census information about these children, if you'd like to have it.
Mary Ann (Bland) Sheargold (first wife of Francis Benjamin) must have died, because Francis Benjamin married her sister Eleanor Bland on 19 July 1841 at St Pancras Parish Church, and they had a daughter Nancy (c1851).
I have no information about Matilda Amelia. Louisa Emma was born on 10 January 1812 (she was christened in 1814, as you know). Henrietta Field Sheargold married Peter Henry Valle in 1833. He died in 1847, and Henrietta died in 1854 in the Isle of Thanet, though I foolishly forgot to write down my source for this.
Do you know of any more Sheargolds of the generation of Henry Joseph? I'd be very interested to hear from you!
