Allan Morrison (June 3, 1803 – November 21, 1877), alternatively spelled Allen Morrison, was a Canadian-American fur trader and politician who served in the House of Representatives during the first session of the Minnesota Territorial Legislature.
Morrison was elected to the Territorial House of Representatives in 1849, following the resignation of William Sturgis. He was a representative until the session ended at the start of 1851.[3]
Morrison, with his brother William, became the namesake of Morrison County when it was founded in 1856. This was in large part due to the fact that Allan forwarded a letter to Alexander Ramsey detailing William's exploration of Lake Itasca. Ramsey circulated the letter and gave it large publicity, perhaps influencing the legislature to name the county after the brothers.[1][2]
