According to my records, Statira Benson was born 18 Feb 1814
in Cortland County, NY. Her father was Potter Benson, no dates or places, mother unkonwn. No death date/place. The 1900 census of Eldred shows head of household with 5 living
and 4 dead children. I only show the same two children you
have.

Justus Rice, Jr was born 14 May 1814, prob. Eldred, PA, d.
5 May 1889, buried Myrtle, McKean, PA. He was son of Justus
Rice & Polly Barnard. I have much more on this line if you are interested.
