Hi Ann, Just found your message. My name is John Hissett and I have traced my ancestors back to Lincolnshire. My surname seems to have evolved from Issitt / Hissitt. My Great Grandmother was christened Eleanor Issitt Tindale. When her parents married her name became Ellen T Hissitt.
I have my own web site at www.jhissett.pwp.blueyonder.co.uk/ where you can see my family tree. I am adding details all the time.
