I found him on the WWI Draft registration records, and his full name on it was listed as Thomas Clairfoyt Gebhart, born 20 Nov 1895 at New Roads, Louisiana. At the time of this recording he was living with his wife in Addis, Louisiana. Although I did find him and family on the 1930 census, there is no record of him on earlier census records. I also can not find him on the SSDI records. Do you've any idea when and where he died? Have you tried obtaining a death certificate to find his parents names?
