[1] Girard's country home was on a plot of land he named Gentilhommiere in what was formerly called Passyunk Township of Philadelphia County.

He was likely the richest man in the United States when he died in 1831, and he left most of his $6 million estate to the City of Philadelphia.

Girard's will stated that the city must establish a school for poor orphaned white boys in his name,[2] and that Gentilhommiere must not be sold.

On March 15, 1981, Philadelphia organized crime boss Phillip Testa returned to his Girard Estates twin home at 2117 Porter Street and as he was opening the door a nail bomb exploded under his front porch killing him and doing extensive damage the house.
