Jane - well, this development solves some mysteries (but so strange that they all went to the same synagogue as one iff the attorneys. That has to be a total coincidence):
how info was getting from this theater company in midtown NYC to my sister-in-law in NJ, and how the theater company knew details about me that weren't secret but which I knew I'd never had any reason to have shared publicly;
and recently, how Julie had info about my brother's family that I know I certainly never shared with her, as I had no need for her or anyone to have any "dirt" on my brother even when the Fred-Julie joint work was going well. Julie had met Joann and my brother a few times, as a friend of my brother's seemed to have encores tickets near Julie's ticket for a while and they'd get that friend's tickets at times way back). But the family detail had happened years ago, and it might have been of interest to Joann's lawyer - but how it got into Julie's very legal-reading e-mail to me last April was so strange that wrote to Julie if she'd been in touch with anyone in my brother's family - and she hadn't, she wrote back.
But if all had the same lawyer(s) drafting emails for them, the access to the info seems more direct.
