Hi, Anna. You mentioned the Stones and Bones book about Prince George's County, MD. I am positive that a copy (or two) are on the shelves of the National Genealogical Society library in Arlington, VA. You can borrow the book(s) through the mail from them. www.ngsgenealogy.org is web site. [email protected] is the office email address. There are many many books related to Maryland genealogy in that little library. For some reason... I cannot seem to get the library catalog to work this evening, but it is usually quite reliable. You have to be a member to borrow books (for 2 weeks) through the mail ... they don't count transit time. Resources are good and can be had for a "song". Good luck. Jon Strickland PS: Dereka Smith is the librarian and is very helpful. Just drop my name.
