Their house sat along a colonial road in Middle Village from 1719 until 1986, when a greedy developer, over protests of the town, demolished it in order to turn it into Queens crap. The city's Landmarks Preservation Commission helped by not designating this classic example of 18th century saltbox design.
The LPC's disdain for Queens is well-documented. There are just over 50 landmarks in Queens and more than 500 in Manhattan. If this house had been in Manhattan, it would have been landmarked immediately upon passage of the Landmarks Law in 1965. But, alas, it sat in a borough of working class people and immigrants who shouldn't celebrate their past or their architecture, so instead LPC said, "let them eat cake."
