Is there a chance that in any of your research you've come across a "Jack", "Sam" or "SJ" Irby? This was the father of my great grandmother. He was not present in her life, so our family knows nothing about him. He went by Jack, but a few censuses I've found from 1930 and 1940 show him listed as Sam J and SJ. He was born in Choctaw County, AL on May 17 1885, but the census lists that his parents were born in MS.
