I'm looking for information about a Sarah Jane Longfellow born during December 1815. Family tradition holds that she is a cousin (2nd if I remember correctly) of Henry Wadsworth, but I have yet to find confirmation of that. She married a William C Dexter on December 31, 1837, and in the mid 1800's, the family moved to Iowa near the town of Greene. The couple's children where Coetha (~1840), John Benson Dexter (~1843) and William H. Dexter (~1848). Any info that can start me moving again down this branch of the family would be greatly appreciated.

Thanks,
Darin
