In 1746, William Allred purchased 3 tracts of land in Prince George’s County, Maryland. These 3 tracts had originally been part of a large tract called Piles Delight. William combined them and called them Allred’s Purchase. A survey for Piles Delight allows us to see where Allred’s Purchase was located. If you rotate the survey drawing so it is oriented North-South, you can see how it fits perfectly into a curve in the Potomac River in Prince George’s County, Maryland.
