Unfortunately, the book is very speculative in this area. The author was able to place about half the Dows in Jefferson Maine. The remainder are listed and grouped where relationships are known.
There is a Fred A. Dow, a carpenter, who m Cassie Ham b Winterport. Their children were Clyde Hadley Dow and Norman C. Dow.
It is assumed that this Fred is actually the one listed as Freddie A. Dow b Bangor ME 15 Jan 1865. Freddie was the son of Charles B. Dow, carpenter of Passadumkeag and his 2nd wife Eliza J Lancaster.
Charles B. Dow was b. 1816. His father was Joseph Dow of Palermo. Here's where it is really odd - it seems that he was born Joseph Evans.The book also says that he m. Jennie Sabine, But the record of birth of Charleshas him as Joseph Evans and his wife as Mary J. Dow.
That same area of the book has a Henry Dow who had one son, James H. Dow b. prob. abt. 1835.
