Ruth - My name is Tricia and I am the great granddaughter of Walter Opal. My grandpa was Walter's son, Richard Opal and my dad was Walter's grandson. I unfortunately have little information about him and am searching for more as well. I have some basic elements but not much detail. He was not a man that my grandfather was proud to talk of, apparently walking out on the family repeatedly. You are welcome to ask any questions and maybe I can provide something. As I am not on here very often, email may be faster.
triciagardner@sbcglobal.net. Hopefully I can help.
