John, There is an Otoe County website: http//:www.rootsweb.com/~neotoe >From there, you can Email the coordinator for that site; there is no listing of historical societies on the site itself (at least, none that I found). I've found it's good practice to check the USGenWeb sites for specific counties and states before querying individual lists for addresses, etc. Many have addresses for obtaining vital records, lists of historical societies, and so on. Good hunting, Barbara
