I have some information that might be of some use to you. Elijah Calk had 2 sons who were half brothers, David and Jack.The oldest and I'm not sure which one that is,his mothers name is not known(or wasn't when our information was gathered) the youngest mother was Mary Younce.she was born in S.C. 1785.so Mary was Elijah Calks second wife. They moved to La. from Ala. after the Civil war. I have more information that might be helpful.My gggfather was Moses G.H. Calk and was a full brother to the oldest of these boys.
