6th Great Grandaunt
This same source lists five children: Thomas, Hannah, Rachel, Benjamin, and Susanna. (2) One tree at the Wainwright Family of Essex County, Massachusetts site lists a total of 9 children. (It even has sources.)
I did not quickly spot a death date or additional information, but I now have some information which may help me gather additional documentation on this family. I also discovered an alternate spelling for the surname Andrews ("Andross") which I might not have found in an online search and could possibly have found in a printed index if Andross followed Andrews or was near it alphabetically.
