The Sussex Family History Group was founded in 1972. It has about 3500 members in Sussex, the rest of the UK, and around the world. There are four meeting centres in the County at Brighton & Hove, Horsham, Uckfield and Worthing; if you live in Sussex you are likely to find one fairly near to you.
A quarterly journal, The Sussex Family Historian, is posted to all members as part of their annual subscription. This journal is typically a sixty page A5 document full of articles and information about Sussex. The Group has its own Library and Family History Centre at The Keep in Falmer, Brighton.
