Hi
I know I'm a bit late to this chat, but I just found a connection to the Michael family and thought I'd add a small contribution - Marie Michael was my g-g-grandmother (b 1829), daughter of David Michael, married Henry Cooper Batchelor.
I discovered the connection when I found an inscription on some silver dishes - presented to William Henry Michael by the people of Swansea in 1861 in recognition of his services to the town.
I'd be interested to know more about the connection between William and David/Marie.
