Alexander Bisset Munro was born 25 Dec. 1793 at Inverness, Scotland to Donald and Janet (Bisset) Munro. Alexander left Scotland at the age of 14, and lived in Dimecrana in the West Indies for 18 years. He owned a plantation, raising cotton, coffee and other produce. He brought produce to Boston Massachusetts on the ship of Solomon Dockendorff. To be sure he got his money, Solomon asked his to come home with him, where he met Solomon’s sister, Jane Dockendorff. Alexander went back to the West Indies, sold out, and moved to Round Pond, Maine, and married Jane. They had 14 children: Janet, Alexander, Margaret, Nancy, Jane, Mary, Solomon, Donald, John, William, Bettie, Edmund, Joseph and Lydia.
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.
