Hi Deena, How are you? Margaret (ALLEN) VANNOY McCORD HARRIS and her second husband William H. McCORD were my ggg grandparents.
Here's what I see in Joe Gardner's information: Thomas McCORD m. Jane (DENTON) One of their sons, Isaac Harris McCORD b. 18 Nov 1849, d.12 Aug 1922. He is said to have been named for Isaac HARRIS. Isaac Harris McCORD m. Virginia C. (BLAGRAVES) 15 Dec 1870 in Martin Co, IN. Isaac had a daughter Josephine McCORD b. 1885 and Isaac had a son, Isaac Henry McCORD b. 24 Mar 1891.
Robert McCORD (son of David McCORD and Anne SHIPLEY) m. Pamelia HARRIS 31 Dec 1795. (Don't know if she is related to Isaac HARRIS.)
Let me know what you think. Marilyn (Sause Conlon) Gappa
