Malinda Gorden/John Criss PA>OH mid 1800

I'm looking for parents of John Criss/Crist (b. ca 1800-1810 PA)and his wife, Malinda Gorden (b. ca 1796-1816 PA). They were found in the 1850 & 1870 censuses for Monroe Co., OH. Their children, William, John, Joseph, Elizabeth, Nancy, Mary, Jacob, and Samuel were all born in Ohio between 1828-1848. The 1850 census also shows a man named Samuel Criss (?John's brother?) living with them.
Thanks for any info that you may have!
