Maryland is at its thinist at the town of Hancock which is mid way between hagerstown and Cumberland. Thee it is just a few miles thick. At Cumberland it is about 25 miles thick... about 20 miles from the Potomac River (border between West VA and MD there and Cumberland, another 5 miles or so norht of Cumberland to reach Bedford Co., PA Cumberland is in Allegheney co., MD. Garrett co. is directly west of Allegheney co. and is the westernmost MD County. West of Garrett co., MD the state of Maryland does not exist meaning West Virginia touches Pennsylvania there. Ohio Co., WV in the little ledge of WV that sticks up to PA just west of Garrett co... was one of the original VA Counties to go to WV when WV was first created. can't find any Livingsotns there though at least so far... Like I said bedford Co., PA has a lot of Livingsotns early on but all dissapear by the mid 1800's Need to find out when it was created and out of what parent Counties.. Joe
