HUNTER, LIBERTY and his mom MARTHA 1850

Looking for my Hunter family in Ohio before 1850. MARTHA HUNTER born 1791 in Nova Scotia, I don't know her husbands name, but she had at least 3 children...LIBERTY, MARGARET and MARTHA A. Liberty was born 1819 in Ohio. MARTHA and her family moved north to and settled in Berrien County, Michigan where I found them in the 1850 census. Liberty was married to Elizabeth and they at this time had ANNA C. 7, MARY E. 4 and LUCINDA 3...LIBERTY and family eventually moved to Oceana County, Michigan where i was able to accumlate much more information on him and some of his children...if anyone has any information to help me on this family before 1850, the father's name, where they lived in Ohio, would be very appreciated.
