My Sussex ancestors went to SE Ohio, why I have no idea as the land is NOT good for farming. It was cheap tho' In the 1850 census of Monroe County, OH, there are quite a few people who say 'born in Delaware" Checking them out, they are all interrelated families from Sussex. Okey, Prettyman, Hazzard, Stockley, etc. To get some ideas on where people went after the Revolutionary Way you can try reading Rev War pension applications. They have been abstracted and published - larger libraries usually have copies as the set is rather expensive. Some LDS Family History Centers also have copies. Forget the given name and just read the surnames. The applicants list all the places they have lived since the end of the war - LOTS of good clues about migrations. (There is a master index to this set - don't forget to check it too.) Sorry, I can not remember the author, maybe Cyndi's List would have it or a search on the NSDAR Library site.
