Hello Rita,
I live in Milpitas, which is not the biggest city in
California, hence there is no "active" cemetery in town, with the exception of a few small old-time pioneer graveyards. (In short, Milpitans are buried in our neighboring cities). This is just a stretch guess, but if your great-uncle was buried locally, then there's a good chance you may find him here:
Cedar Lawn Memorial Cemetery, 48800 Warm
Springs Blvd,
Fremont,
California, 94539. Why don't you send them a letter with your request, and please let me know how it pans out. Also, if he is in fact buried there, I'd be happy to take a photo of his stone for you as its just a few minutes up the road from where I live. Good
Luck!!! Bob.
