Pioneer Thomas Cresap

Thomas Cresap was known in Western Maryland as a "border ruffian" and in Pennsylvania as the "Maryland Monster". In the 1730's he tried to expand the borders of Maryland at the expense of Pennsylvania and Virginia by settling German immigrants into disputed areas and surveying the source of the Potomac River as far south as possible. Only in 1746, with the arrival of Mason and Dixon from England, was this dispute finally resolved.
