I have seen the name spelled three different ways just on papers that the family has. My Grandmother was Olga Trudal, b. 1888 in Switzerland I believe. She had two older sisters, Julia and Elsie, and, we think, one brother,Arntt. I have no idea when Julia died but it was before the 1950's. Elise died in 1953 or '54. Olga died in 1961. The family settled on the Southside of Pittsburgh, Pa. I know there were other relatives on the southside and in Eden Valley,Pa. If you have any information on any of these names please write to let me know.
