"Does any of this sound familiar to you?"
No, it doesn't sound familiar but I wonder if I might tie into it somehow. I have John Banks [abt. 1780 - 1836, Castle Combe, Wiltshire] who married Elizabeth Jones [abt. 1790 - 1782, Chippenham, Wiltshire] in 1804 in Castle Combe. They had, as best I can make out, 13 children: John Jones, Frances, William, Worthy [my ggg-grandfather], Jane, Charlotte, Eliza, Samuel Simon, Silas, Elizabeth, Enoch, Ann and Jesse.
