I believe there is at least one in Thorne and in Free Cities, although we may have to go looking. It seems like one of those families who works everywhere so has point people in them.

[ Natasha and Lucifer did actually find the one in Thorne in another investigation. ]

We can't assume all of them were a part of this, but they may have information all the same. Religious fervor like this does tend to run through families but she could be an exception.
