In the spring of 1843 Jacob Fisher made a claim on unsurveyed lands at the head of Lake St. Croix, immediately south of Dakotah, spotting and blazing the trees to mark the limits of his claim. Mr. Fisher thought it a good site for a saw mill, and made an offer to Elias McKean and Calvin F. Leach of the entire claim on condition that they would build a mill. McKusick and Greely were looking for a mill site; Mr. Fisher referred them to McKean and Leach. It was agreed that the four should take the claim and erect the mill. Greely improved and held the claim, while McKusick went to St. Louis and procured mill irons and supplies. McKean and Leach operated in the pinery. By April 1, 1844, the mill was finished and in operation. This was the first frame building erected in Stillwater. It stood on the lake shore, east of Main street, lot 8, block 18. The second frame building was McKusick's boarding house, west of Main street, on block 18. John Allen's family was the first to locate in Stillwater. Mr. Allen came in the spring of 1844, and subsequently removed to California. The second family was that of Anson Northrup coming soon after. Mr. Northrup built a public house on the west side of Main street, just north of Nelson's alley. Soon afterward came widow Edwards and family from Ohio, relatives of the Northrups; Mrs. Northrup being a daughter of widow Edwards. Socrates Nelson came about this time and built the first store in Stillwater. His family joined him soon afterward. The first marriage was that of Jesse Taylor and Abbie Edwards, J. W. Furber, Esq., officiating justice. The second marriage was that of William Cove to Nancy Edwards in May, 1845. The first white child born was Willie Taylor, son of Jesse Taylor, in 1845. A daughter, Maud Maria, was born to Mr. and Mrs. Paul Carli in Dakotah (Schulenburg's addition to Stillwater), in 1843. Stillwater derives its name from its appropriate location on the banks of the still waters of Lake St. Croix. A post office was established in 1845, and Elam Greely was appointed postmaster. The first business partnership was that of the saw mill company, already noted. We give here in full the articles of agreement as the first written and the oldest on record in Washington county. This document is important not only as fixing a date for the origin or founding of Stillwater, but as an important event, as it thus early laid the foundation of the future prosperity of the city, and indicated the direction in which its energies should be chiefly turned: [_Copy of Agreement._] This agreement, made and entered into this twenty-sixth day of October, Anno Domini eighteen hundred and forty-three, by the following named individuals, viz.: John McKusick, Elias McKean, Elam Greely, and Calvin F. Leach, for the purpose of building a saw mill near the head of Lake St. Croix, Wisconsin Territory, and for carrying on the lumbering business in all its various branches.
