Page "Frelinghuysen Township, New Jersey" Paragraph 1

Frelinghuysen Township was incorporated from Hardwick Township on March 7, 1848.

According to the book Historical Sites of Warren County, the township was named after the Honorable Theodorus Jacobus Frelinghuysen, a minister and theologian of the Dutch Reformed Church who came to New Jersey in 1720.

Theodorus was the grandfather of Theodore Frelinghuysen, the noted statesman, educator and running mate of presidential candidate Henry Clay on the Whig Party ticket in the 1844 election, and who is also credited as the inspiration for the township's name.
