I don't know if this is the family you are looking for or not, but in 1839 A Horsey Smith and family went from Ohio to Linn County with Perry Oliphant and family. Perrys oldest son was named Edward Horsey Oliphant.
Not much is mentioned in the records that I found in Linn County. They may have been related as another Oliphant was later named Horsey. Perry was my wifes gggg grandfather. They came to Ohio from Marlyand between 1800 and 1806. Perrys father William Oliphant died abount 1832 and is buried in Circleville, Ohio.
I have always been interested in the name Horsey as it is such an unusual name for a person. I have no other knowlege of any family member of this family. I would like to know if Horsey was related to the Oliphants.
