Are you aware of Mary Oldfield, b. 1783 in Orange Co., NY or Sussex Co., NJ who m. 1. Eli Kelsey in Ontario Co., NY, but by 1834-37 had six children (4 sons, 2 daus) then m. 2. John Pierce. He died, they say, near Cincinnatti (she may have had a brother in Portsmouth, OH). She became 3. an unofficial wife of Brigham Young, prob. in Nauvoo, IL. Why? My guess is that any of her Oldfield children joined the LDS. Later she married 4. John Brimble (?) in Utah; it might even have been around Pleasant Point/Hill...something like that.
