Evan - my family live a few hours away by car. I don't know where my sister lives - I thought she lived at home with my parents when she wasnt at bethel - but I presume she lives with her husband!
Wouldn't you then be able to go down and pay them a visit, it would be hard for them to ignore you if your at their doorstep right? Or at least ask for your sisters location...
If what Defd told me was true in another post, some jw's take the shunning too far, maybe the local elder might help.... Idk just an idea
I'm sure you probebly thought of all these already...
But anyway... i'll keep you in my prayers Crumpet
