Hello, Gary, my name is Bonnie Thompson. My mother is Lois Traeger Thompson, and her mother was Elinor Meissner, Emma's sister. Elinor married Fred Traeger, and they lived in Des Plaines, IL. So, Emma and Ralph were my great aunt and uncle, and my mother and your father are cousins. I've been to your father's home in El Cajon. I'm a writer/author. Hats off to Ralph and Emma Brengle and their wonderful donation of "Brengle Terrace Park" in Vista, CA!
