Osage County,Kansas Marriages
Just found this web page of Osage County Marriages:
http://www.kscourts.org/dstcts/4osmarec.htmThe page shows it is through 2001, but doesn't say when it starts.
Unfortnately, this is a grooms index. If all you have is the bride's name, it appears you would have to go into each groom page and do Control-F to look for the bride - unless there is a separate web page like this with the brides indexed.
