Book of Dow has an Aaron Dow with wife Mary b. 1780. Aaron was b. ca 1775, son of Moses Dow and wife Elizabeth. Moses was the son of Judah Dow.Aaron had a son Moses b. Seabrook ca. 1807. Moses m. Hannah ???, was a shoemaker, and died 1869. 6 children.
This is all from The Book of Dow, and I can't verify its accuracy.According to the book, Judah was the son of Joseph Dow and his 2nd wife, Hannah, a child of indian parents who had been taken from them with full permission and educated as a Christian.I have a separate article written by George Freeman Sanborn, Jr. which totally refutes this story, and identifies Hannah as Hannah Challis, sister of Joseph's first wife, Mary Challis. In the detailed article which appeared in the New Hampshire Genealogical record, he does provide the line from Joseph > Judah> Moses > Aaron. He does not give additional details on Aaron in this article - just that Aaron was b. ca. 1775.
