Go to Cyndi's List, then to MD, then to Frederick County, and look for "Lookup Volunteers" or "Books We Own." You might want to stop at just MD first...I think the Myers book is all MD. I had some lookups that way. There are also probably others on Frederick MD GenWeb. Also just look at the list of books, Barnes? has a lot. My marriage is NOT in Myers...or anywhere. (not my own, but my ancestor's!) I can't remember how late the Jacob Engelbrech Marriage Ledger goes, I only have pages copied for O'Neill, people will also do lookups in that. Well now that I think of it, one of the marriages is 1849. PS. There is a lot of movement from Frederick to OH, I have it in my ancestors, some of them going back and forth, but not to that county. Barbara Ford PS. I tried, you can't get any of these books on interlibrary loan.
