I also have three books of Henry Co.,IL marriage records Book O 22 Aug 1837 to 7 Jan 1854 Book A 18 Jan 1854 through 30 Jun 1869 Book B 5 Jan 1869 through 5 May 1878 I also have a transcribed and indexed 1850 Federal Census. If you feel your ancester might have "crossed the line" from Bureau Co, IL, I'd be glad to look up a few names. Diana
