Jane, Perhaps I can help clear up a few of your mysteries. The URL below shows the development of hundreds in Prince George's County. Washington Hundred was formed in 1777 from Mattapany, a hundred that was formed when the eastern lands of PGC were still a part of Calvert County. http://www.rootsweb.com/~mdpgeorg/text/hundreds.htm Scroll to the last map. You will see that Washington Hundred is not near Washington DC at all. It is in the southeasten part of PGC. The naming convention that I have found in a number of English families that I have researched is as follows: First son is named after the father's father. Second son is named after the mother's father. First daughter is named after the mother's mother. Second daughter is named after the father's mother. I am making no claim that this is the one and only naming convention, but have used it successfully to track several parents down. Knowing that Edward & Ann married in 1786, and with information derived from the 1790-1810 census data, you probably have an idea about how many children Edward & Ann had and about when they were born. The number of children under 10 in 1810 also provides a clue to when Edward either died or left the family. A low count may indicate the date closer to 1800. A higher count suggests a date closer to 1810. From the information you have given, you have identified William as a child of Edward and Ann and Amy as a possible child. Were there more indicated in the census? The best place to look for information on these families is the land records. Start with the index. You may find that Ann or Edward deeded land to other children. Look for Thursby to Thursby transactions and also check for any Thursby to Singleton records. Land records involving the settlement of an estate contain the names and locations of all the heirs. You may even find records pointing to Edward's parents or siblings. Even though Edward didn't have a will, there ought to be an accounting of his estate in the Orphan Court records. If you know what religion this family followed you may be able to track down church records. Their burial records may be included in "Stones & Bones."
