I am at a "brick wall" with my great-grandfather, Leonard E. "Buddy" Prothro. I can't seem to get beyond him to who his parents may be. The information I got from the SSDI does not provide his parent's names. He is on the 1920 Federal Census with his wife, Arelia Bryant Prothro and my grandfather, John L. Prothro and his siblings. There is a Joe Prothro listed just above Leonard's name, on the 1920 Census, who may be his brother and a man listed as "father" (under Joe's household) but I cannot make out the name. Leonard was born in 1890 and died in 1979. He was a native of Natchitoches Parish in Louisiana. If anyone has any information, or any tips on how I might get further on this, it would be greatly appreciated.
