History
Directly west of Sand Beach township lies that of Sigel. It was organized some time prior to 1864 with Watson Robinson as the first supervisor on the records. He took up of land under the homestead act that same year. In the fire of '81 all of his buildings and crops were destroyed. He found himself the morning after the fire without a hat or shoes and practically destitute of clothing of any kind. With his accustomed energy and enterprise he began at once to rebuild and repair as far as possible the damage done by the fire. The first settlers in this township were Fred Jurgess, Joseph Lakowski and Waterhouse Whitelam, who came in 1859. Samuel Williams was another pioneer in this section of the county. In the early lumbering days he had worked for Pack, Woods & Co., at Harbor Beach and later at Port Crescent. He moved on to his farm in Sigel soon after the fire of '71 and by diligence and hard labor transformed this piece of land from the wilderness that it was in 1874 to the modern country home of the present day.
