Joseph Henry Aaron and Dora McKinley

My GGGrandparents Joseph Henry Aaron and Dora Ann McKinley. Joseph was the son of James Henry Aaron of Kentucky and Elvira Walker of Crittenden Co. Kentucky. Dora Ann was the daughter of John Raymond McKinley of Ill. and Rebecca Marvel of Crittenden Co. Kentucky. Joseph and Dora had 7 boys and 5 girls. Joseph died in Kentucky in 1922 and Dora Ann moved to Texas to live with my Ggrandfather John Richard Aaron. She died in 1950. I am not sure who the child is but assume it was one of their seven sons.
