Julie, Yes, we are talking about the same family but I am confused as to the age of your ISAAC. My James was born abt. 1804. He had a son named Isaac O. who was born in 1842 and died after 1910. This Isaac had a son also named Isaac M. who was born 1874 and died 1920. The Isaac you speak of with Amy etc. was my James' son. I do not have any siblings for James. Wish I did! How are you connected to the Clarks? Maybe we are cousins! Betty
