HISTORICAL SKETCH (about his Uncle Jesse - who became his step-Dad - when his biological father died): just prior to the formation of the "Ouisconsin Territory" - in the fall of 1835. In the company of Sewall Andrews (founder of Mukwonago, Waukesha Co., WI.), Major Jesse Meacham and A. Spoor accompanied him from Chicago {then, a mere 3,000 souls -ed.} to Milwaukee Village {which was just being settled}, where Milo Jones joined them, proceeding with a team, to the southwest, they tented-out on the open prairie, now the site of the city of Janesville, returning via Chicago, to his native State, remained until the spring of 1836, came to Milwaukee, met Henry H. Camp, and with him, reached the Indian village of "Mequonago", in May, 1836. Major Jessie Meacham was one week ahead of them, a present of two barrels of flour induced the Indians to allow them to build a bark roofed shanty, 10x12 feet, in their village, prior to this, they built, but did not occupy, a similar hut on Sec. 22, these were very first log buildings ever erected by a pale-face in Mukwonago, the "Logs" were removed in 1837, but many returned and staid for years, the village plot was surveyed by Martin Field and Ira Blood, in the fall of 1836, in the spring of 1837, Mr. A. built a store and brought-in the first goods from New York City, this was the trade center for twenty-miles around, and the hardy frontier merchant reaped rich rewards, after relinquishing mercantile business, Mr. A. owned the grist mill five-years, but of late, has given his attention to cultivating his farm on the outskirts of the pretty village, in which, he is now the oldest settler, his substantial brick residence was built in 1842, and was one of the first of that material erected in Waukesha County.
