So, doesn't that imply that a message that claims to be from Andrew Tyler via the list will have originated from Andrew? In which case, I’m still intrigued what Andrew’s connection to Katherine Black is, as I think he didn’t start ringing in Boston until long after her ordination, and left well before that thank you note became an issue.
Sorry if I’m being dense. Well, denser than usual.
