Not sure just what information you are looking for, but this sounds like the family of Joseph Dow and Olive Cobb. They had children Joseph Enos, Sallie, Melita, Lorenzo, Philena, and George Peck.Philena m. Christopher Palmer Tallman.George Peck Dow m. Luania Prentice, and had 4 daughters - twins Elvira Philenea and Elmira Luania, and then Olive Cobb and Mary Belinda. Mary m. Edgar Joseph Sanford. Looks like enough similarities in names to be connected. I don't see an Amy Alice - there is an Alice L. with a sister Lydia who m. Edward Tucker.The Baldwin name also appears - Enos m. Miranda Baldwin.
This is all taken from "The Book of Dow," and I have no independent information to verify its accuracy. Email me directly if you think additional information on this Dow line might be helpful to you.
