I got the 2nd glider from a different source (Craigslist IIRC). 2nd glider was actually offspring from a PP pair, which might explain why she is much smaller. They are definitly unrelated.
I'm beside myself still. I cannot believe that I thought I had a male... ugh. I handle them nearly every day, and let them run about the bedroom several times a week. I check claws, and teeth often... never once did I think to 'double check' sex. I've had animals of every kind and consider myself well experienced. Just goes to show: No matter how much reptile/cat/dog/rodent/bird experience you think you have... jumping into glider world means you may know nothing. Or at least might need retraining.
So... now I need to fathom getting a male. I could get one for nothing most likely, as I have a buddy that has two outdoor colonies. I would just need him to be young since his colonies are unhandled and 'wild'.
