I think I can help you with your search. I,too, am a descendant of Geo M Gleason. I have just been trying to put together what I can glean from Perry Co. IN records. Geo's daughter Mary Jane gleason is my link to the family. I will be able to help in any way I can. I lost track of Melvin in Oklahoma I believe.
Let me know
