I believe I have finally found the link of my family ancestry from the US to England. I have located who I think is my GGGrandfather, John Sambroke (or Sambrook) de Rockstro, b. November 5, 1810, but I would need to verify his emigration to America, possibly Canada and then on to New York before 1874 when my Great Grandfather was born. Can anyone help, please.
my last name at birth is de Roxtro, so similar. John Sambroke simply MUST be the link.
