At this time I have found no names connecting Harry S.Truman to the CSA. I have looked at close to 100 different websites that suggest a connection, but the connection is not named. I did not check all of his cousins and uncles, if the info was not posted to the website, I moved on. It seems his mother's hate of Yankees comes from incidents during the WBTS.
If anyone can prove this connection please let me know.
Thanks,
GP
