Elmer and Lorraine had two children.
Druzilla died young as a result of complications from injuries sustained in an auto accident, as I recall.
Ted seems still to be around, retired by now. He is credited as having donated a lot of Elmer's guns and stuff for the Cabelas display. I am pretty sure Ted produced some grandchildren, I recall a family picture in one of my Keith books, lost to fire in The Incident.
