Well, really, she's just answering your specific question.There's a ton more she can tell you about States Barton Flandreau and his various wives and progeny, if you're interested.
In the meantime, I concur with the Sherry's note about States Flandreau's parents, although I don't know if there is specific evidence that Ophelia's maiden name was Barton.
Here's a relevant census entry:
1850 New Rochelle, Westchester County census: Dwelling 47, Family 55 William Flandreau, 39, male, Shoemaker, $300 in property, born in New York Ophelia Flandreau, 40, female, born in New York Charles V. Flandreau, 11, male, born in New York, attended school during year Staats B. Flandreau, 9, male, born in New York, attended school during year Pheebe J. Flandreau, 7, female, born in New York Mary C. Flandreau, 4, female, born in New York John W. Flandreau, 10/12, male, born in New York
States' name was difficult to read, but I think what I have here is what the census taker wrote down.It amy be notable that there are some families in New Rochelle with Staats as a surname.
