Thank you again. Some months ago, I looked at the Family of Thomas Rogers Through Five Generations which was revised by Ann T. Reeves. The children of Josiah Washburn and Sarah Richmond are the same as in the reference you gave, but for some reason I have reversed the order of the first two children, Mary and Josiah. I have Mary b. abt. 1727 and Josiah b. abt. 1729, whereas, Barbara Lambert Merrick, has it Josiah Washburn born ca. 1726 at Bridgewater, and Mary Washburn born ca. 1729. As for the two younger sons, both dates of birth are the same for both sources.
