Stephen and Hannah (Beebe) Hungerford had three daughters--Elizabeth, Julia, and Mary Fidelia and several sons (none being Hiram.)I show him living in Oakland county, Michigan in 1840.
I have one Hiram who was born in 1844.He was the son of Hiram & Lucinda () Hungerford.Hiram's father Hiram was living in Van Buren county, Michigan in 1840.I don't have a Sarah listed for this family either...There are two sisters--Nancy L. & Lucy Ophelia.
I don't know if this additional data will help or muddy the waters.
Barney Hungerford does have several as yet unkown daughters...
