I have seen John Lycans name with an S. and a D. for the middle name. I have John D. Sr. Lycans, b. Dec 26, 1804 Illinoise. I use the Sr. because he has a son named John D. Jr. Lycans, b. Abt. 1828 Pike Co., KY. Mose Lycans was married to Emaline Milum (Milem), b. Bet. 1839-1840 Wythe Co., VA.; married on April 26, 1860 Pike Co, KY. They had a daughter named Anna Lycans, b. 1871 Pike Co., KY, (she is my great grandmother)
I don't know if you can use this info or not, but just in case.
