Some time between 1766 and 1768, Alexander Campbell removed from Damariscotta to Steuben, and built a mill at Tunk, now called Smithville, on the east side of the river. It was the first mill there. In 1759, he married Betsey Nickels, who was born in Ireland and came to Lynn, Mass., with her parents when about six years old. From Lynn, she came with her brother, Capt. William. Nickels, to Damariscotta. Children of Alexander and Betsey Campbell were: James, Frances, Hannah, Peggy, Polly, William, Samuel, Alexander, and Betsey.
