Looking thru my RAY material I find a Catherine VOTH who married a Abraham ILLK. The ILLK and RAY families have several connections in the Vermillion Co., IL area.
(1) Elva RAY (b. 23 Apr 1867 Catlin, Vermillion Co., IL) md. Samuel ILLK. She is d/o John Robert RAY (b. 4 Jan 1844 IL).
(2) Albert Marion RAY (b. 18 July 1857 IL) md. Julia Olive ILLK (b. 4 Nov 1858 Oakridge, IL), d/o Abraham ILLK. Albert is s/o William M. RAY and Rebecca M. BOGGESS.
This is a long-shot. Don't know if there is any connection or not. The names of Robert and Martin are common names in this RAY family of Vermilion Co., IL.
If you think there exist any connection, let me know names, dates, and locations, as I have much more on this RAY family.
