Linn was born in Bedminster Township (now Far Hills) in the Province of New Jersey in 1749.[2] He was the son of Margaret (née Kirkpatrick) and Judge Alexander Linn,[3] an Irish immigrant who became a prominent Judge in Somerset County.[4] An uncle, Joseph Linn, was a prominent landowner and paymaster during the Revolution.[3]
After graduating, he was the librarian of the college for a year, then studied law, was admitted to the bar in 1772 and commenced practice in Trenton.[5]
Linn was elected as a Republican to the Sixth Congress, serving from March 4, 1799, to March 3, 1801; he was not a candidate for renomination in 1800 to the Seventh Congress.[1]
Upon his father's death in 1776, he inherited his family's 664-acre estate, which included 20 slaves, in Mine Brook Valley.[5] After his first wife's death, he remarried to Penelope Alexander.[5]
Through his only surviving daughter Evelina, he was the grandfather of Evelina Linn McLean (d. 1840), who died young, and Princeton graduate and lawyer, James Linn McLean (1834–1914), who married Amanda Mixsell. After her death, he married Josephine S. Dunbar (b. 1844).[6][12] In 1871, McLean served a term in the West Virginia State Legislature.[12]
