Philip had been living in Maryland about 14 years when he inherited from his father, Col. Richard Lee II, Esq.
(1647–1715), a tract of land at Cedar Point in Maryland called the “Lee’s Purchase” plantation, of Stump Dale, on the Potomac River in Charles County.
Philip’s home plantation was his Prince George’s County seat, where all of his children were likely born.
It had stained glass windows, a winding staircase, and at least one of its lower rooms had a floor tiled with marble and slate.
Blenheim was not supported by a vast plantation but by income-producing investments and inherited lands and wealth.
The Lees owned other land in the county, but Blenheim was the principle dwelling plantation being a 225-acre (0.91 km2) tract originally known as “The Three Brothers”.
It has been incorrectly identified as that of “Laidler Ferry Farm”, which is located near the present Governor Harry W. Nice Memorial Bridge.
