Frelinghuysen married Emily Macy Brewster. Together they had three children: • Victoria Frelinghuysen (1907–2002), who married John Grenville Bates Jr. • Emily Frelinghuysen, who married H. Edward Bilkey until his death in 1950 and later married Dr. Ross A. McFarland of the
Harvard School of Public Health. •
Joseph S. Frelinghuysen Jr. (1912–2005), who married Emily Lawrance (1911–2004), the daughter of
Charles Lawrance (1882–1950) and Emily Margaret Gordon Dix, and the granddaughter of Rev.
Morgan Dix (1827–1908), the rector of
Trinity Parish. Swiss-born American artist
Adolfo Müller-Ury painted a portrait of Frelinghuysen's wife and son in 1916; it is today in the Newark Museum, New Jersey. Frelinghuysen owned an 88-foot houseboat,
Victoria, that Harding used for 12 days after he won the
1920 election for President, but before he was
inaugurated in March 1921. Frelinghuysen died on February 8, 1948, in
Tucson, Arizona, and was interred at St. Bernard's Cemetery in
Bernardsville, New Jersey.
Legacy A memorial plaque was placed on the estate grounds commemorating the
Knox–Porter Resolution. Today the estate is long gone and
suburban sprawl has replaced it with mini-malls. The marker remains in a patch of grass near a
Burger King parking lot along
Route 28, just north of the
Somerville traffic circle. == References ==
