Bob ... This is my direct line. Jonas Corman + Margaret Zike had 10 children, all born in Wilmore, Jessamine County, KY. In the following order: Alpheus born 1845; Andrew Jackson born 1847; Elizabeth born 1849; William Matthew (my great grand father) born 1851; Franklin P. born 1853; Annie P. born 1855; Sarah Margaret (Meg) born 1858; Henrietta born 1860; Mary Susan (Mollie) born 1863; and Robert E. Lee born 1866.
Jonas T. Corman + Margaret Zike are buried in Woodlawn Cemetery i Independence, MO. I've seen their gravemarkers. Also you should be aware that unfortunately, there are errors in Fanny Dean Corman Mathews' book, in spite of her care to avoid them. She died the same year the book was published ca 1976.
