Franklin County was formed from part of Oneida County in 1913.
Most likely died prior to 1855 because that is when his wife Martha was married to Thomas J. Phelps (The two, Horrace and Martha, could have also divorced but it is more likely that Horrace died).
Martha Ann Davenport
Indicates that her Spouse is Thomas J. Phelps PIN#996036. Could have also married Harrace Marble because of the designation of the two in the 1850 census in Pottawattamie, Iowa.
