I'm hoping you get a reply of some sort from your uncle.
It was rather interesting years ago when I heard a great uncle of mine had died. I wrote a letter to his widow explaining how I remember from my youth the kindness uncle showed my mom, his neice, and her children. Especially at Christmas time.
The odd thing was I explained briefly about my now Jw family and I having no relationship due to that religion, and then it dawned on me DUH- that she was a witness or her kids..or some such thing.
Nonetheless, my letter was never acknowledged, and that's ok, too.
My df aunt is the best. If your uncle is as cool as some of the other old timers long gone from that filthy religion, I'm betting you hear back real soon.
