I am now looking for the Carroll Livingston Dunn and Viola Fern Poole's marriage record. The information I have is that they were married on 30 November 1930 in Monticello, Illinois. Monticello is in Piatt County; therefore I sent an email today to the Piatt County Historical and Genealogical Society. I'll post on this site if I receive a response from them.

Twice I tried to send an email to the historical society, but it bounced back both times. I will have to send a snail mail to them instead.
