Thank you to fellow members of the Maine Genealogical Society for help in deciphering names in this document.
Extract of an 1811 Mortgage of Jonathan Dana Clark (abt 1756-1817) of Berwick, Maine, to Abigail Emerson, Widow, in the amount of $256 for her purchase of 140-1/2 acres of land in Berwick, in the area of Chadbourn's Pond and Great Works River.
Note: Berwick was much larger in 1811 than it is now; South Berwick was set off in 1813 and North Berwick in 1831, with other portions set off later.
Read the original instrument on page 57 of Book 87 - scroll to the next image. The extract notes that the acreage was bounded by land owned by Chadbourn, Grant and Merriam, but the original goes into far more detail.
If you have information to share on Jonathan Dana Clark, Widow Abigail Emerson, William Frost or the abutting landowners, please leave a comment for the benefit of fellow family researchers.
