Hi All
My dad always said that his g grandmother was Spanish (probably true as her name was Da Costa), but he said that he was descended from the Carreras tobacco family and that his descendant was the black sheep of the family and fled to England! As I haven't so far traced the Da Costa lady, I can't confirm that but I suspect my dad made it up.
The other rumour comes from my mother, she always said that we were related to Emma Hamilton, Nelson's mistress. I have recently read 2 biographies about her and in both it is stated that she was born Amy Lyon on 26 April 1765, in Ness on the Wirral, Cheshire, which at the time was a huddle of thirty or so miners' hovels. Her mother was called Mary Kidd and she moved to Ness from Hawarden, a village outside Chester, to look after her newly born nephew. (Men out numbered women 5 to 1 in Ness!). I do have lots of descendants from a different part of Cheshire, but they were, like lots of others, agricultural labourers/farmers/butchers, but lived a long way from the Wirral. If there is a connection, I have yet to find it and I am back to 1740 with the largest branch of the family.
