Seek descendants of Miss Margaret J. CADWALLADER who was in grade school at Havana, Mason Co. IL on 18 March 1863. I have a certificate of qualification to second grade signed by W. E. KNOX, School Commissioner. Will be happy to make copies for descendants. Please send requests directly to kathyhoover@att.net. I'm unsubscribing from this list as soon as I post this because I personally have no ancestry in Mason Co. IL.
