From a family history, I have a Thomas Roberts, a green grocer, born in Germany, married to Martha Roberts, he moved to England, where his children were born. Not sure if Martha was English, assuming she was.
Thomas, silversmith Richard, silversmith Edward, silversmith, soldier in British Army Martha, born 1785, married Lawrence Breyer, 1815, imm to US in 1832, had several children, most born in England. Henry Allen, baker, left for Australia where he was an auctioneer.
Hoping someone else is working on these families. Martha was my 4th great grandmother-
