I didn't know Isabelle. Lester and my grandmother married about 1943-44. I haven't been able to find marriage records yet. My grandma Earlene is buried in Paradise CA. She passed away in 2003. My dad (Robert White mentioned in the obit) remembers Lester, of course, and Bill Wolf, his son.
Again, thank you for posting the obit.
Best,
Teri
