Looking for George Updegraff B Mar 1838 Iowa

This George Updegraff was found in 1858 in Trenton Twp., Henry Co., Iowa. He had a daughter, Nancy Ellen, born in Arkansas in 1877. In 1900 he was living in Indian Territory, OK, close by his daughter, Nancy, who had married John Wesley Ray. In 1910 he was living with Nancy and John Wesley. That's the last I know. I need information about his life between 1858 and 1877. Who did he marry? Thank you.
