Hi there, my Bulgin family came from Somerset too! All I have at the moment is that Elizabeth (Betty) Bulgin married Anthony Stower in Dowlish Wake, Somerset on 30 Jul 1777. Her son, Thomas is my ancestor. Elizabeth Bulgin died on 22 Oct 1826, in Cudworth, Somerset, aged 68 and therefore, by my calculations was born about 1758. A generation later, the family, like yours, came to London.Is this of any interest?
