I found a reference to Isaac Loper on the Ancestry.com Book Indexes alluding to an Isaac Loper that was listed on pg. 339 of the "History of Greene County (Ohio)" by George Robinson. In researching this clue, I found there are two Isaac lopers, born about 1806. Mine born in Pennsylvania and married first to Charlotte Grey and second to Mary A. (Stone) McCorkhill. The second Isaac Loper (II), born about 1806 in New Jersey, married first to Sarah who gave this Isaac Loper II seven children.Isaac loper II then married a Mary who gave him a child, George. (Bn.11 Oct 1869.) Isaac Loper II had a son named Arthur (Bn 3 Mar 1858) who was married to Nannie Ellen Nunnally. I could never find an Arthur married to a Nannie Ellen Nunnally in my side of the Loper family. This seems to clear up this slight mix up.
