Abraham Redwood Ellery and Sara (Sarah) Charlotte Weissenfels had a daughter Martha Maria Ellery (1803-1880) who married Elbert Jefferson Anderson (dates unknown/date of marriage unknown). Abraham and Sara apparently had a son named Abraham Redwood Ellery who died at 12 years of age. Abraham Redwood Ellery graduate from Harvard Class of 1791.
I want to know more about Martha Maria Ellery. I am also curious to know how Abraham Redwood Ellery made is fortune (if he had a fortune). I've been unable to locate much on him except what I wrote above. Anything you know would be helpful.
