Alexander J. Irwin

Alexander Johnson Irwin (March 1, 1799 – June 14, 1847) was an American merchant and Wisconsin pioneer. He represented Brown County in the Legislative Assembly of the Wisconsin Territory during the 1st and 2nd legislative assemblies.

Early life Born in Greensburg, Pennsylvania, on March 1, 1799, Irwin moved with his family to Detroit, Michigan Territory, and then to Green Bay in 1823. Irwin was allowed to occupy the seat while a committee investigated the election challenge. Ultimately, the committee found in favor of Irwin on questions of the vote count, but highlighted the issue that at the time of the election, Irwin was also serving as postmaster. In the federal act which established the Wisconsin Territory, it was prohibited for an existing officeholder to be elected to the Legislative Assembly. Therefore, the House voted in favor of McWilliams. The Council agreed with Irwin's position, and voted to remove Dickinson and install Irwin.

Land office In 1845, he was appointed receiver of the Green Bay Land Office. Elisha Morrow was appointed receiver to fill the vacancy left by Irwin.
