There is very little to add in the book "The Emison Families Revised" by James Wade Emison, Jr., privately printed 1954. It only lists the four children: Ralph Waldo, Redger, Leila, and Lillie. No birth dates shown. It show Dr. Isaac's death as being 3/29/1941 St. Louis? the wuestion mark is in the text. A foot note states about Dr. Isaac H: "Dr. Isaac Emison, his father, was born at Bells, TN, He practiced medicine in St. Louis, and thereafter traveled for the Meyer Drug Co., until his death." Sorry I couldn't help further.
