Hi Listers, If you ancestors were among the inhabitants of parishes in the the Forest of Kingswood such as Bitton, St. George, Mangotsfield, Siston, Wick & Abson and St Philip & St Jacob, you may find your family surnames in D. P. Lindegaard's The Kingswood Index. http://www.bristolfamilyhistory.co.uk/kingswood-index It's well worth a look. Josephine
