Settlement along the Sheepscot River by colonial settlers began in a significant way only with the end of hostilities with Native Americans in 1760. In that year, Lincoln County was established, and in 1761 Doctor Silvester Gardiner acquired a land grant that included the Head Tide area. One of his early land sales was to David Nelson, who built the first dam. Originally part of Newcastle, the village was substantial enough to be set off in 1794 as New Milford (after the large number of mills at Head Tide), later renamed Alna. In the early 19th century the village had six water wheels powering lumber, grist, and textile processing operations, and the village was the town's economic center.
