Person1, sorry I’ve been so late in responding to you. I wanted to qualify my last post. After I read your last post, I realized that you might be assuming that I found out all of these things from the references given to me by the guy. That was not necessarily the case – I just meant they were people I called. They could have been references given by the guy, or references given by the references, or people whom I figured out on my own that they might know the guy.
Regarding #7, it actually may have been a reference given by the guy as I remember being surprised by that myself, but I can’t remember for sure (if not a reference, then a reference given by a reference).
In #4 -#6, in at least one of those cases, the guy himself gave the reference. #3 happened at least two times. In one case, it was the guy’s reference, but it took a while to get the info from him. In another case, the guy himself called the shadchan and asked her to call me to tell me (although that wasn’t the case I had in mind when I wrote the list).
