Ed was the son of Jacob B. and Malita Elvira "Odom" Clements. He married Emma Malverine "Mull" Simmons in 1907. They were the parents of seven children: Dewitt Talmadge, Luet, Earven D., James Earl, Ellen "Dottie" [Tanner], Lewis and Vollen.
It is noted that this family changed their surname spelling from "Clements" to "Clemons". The story handed down through the family is that Ed's father, Jacob B. Clements, changed the spelling from Clements to Clemons, thinking he had killed a man, a carpet bagger, so he moved his family to Arkansas where he changed to spelling.
