Long Segment--But No Close Connection

Particularly when dealing with endogamy, where it is difficult to tell apart cousins who are actually relatively closely related as opposed to those who are very distantly related in multiple ways, a good metric to hone in on matches who may actually be related in genealogically-traceable time is the size of the largest shared segment of DNA.  I've had good success finding people who are actually related or at least are from a very close geographic proximity to one of my ancestral towns, even if we can't find the actual paper trail connection.

But sometimes those large segments may be passed down for many generations.  Several of my kits--all related on my maternal grandmother's side--share the same large segments with several kits administered by a man named Luc.

Another Generation of Diamonds?

I had tested my father's Y DNA several years ago.  As is not uncommon for Jews (who have not had surnames for too long), he had no matches with the surname Diamond besides his second cousin who I'd also tested--but had lots of matches with lots of people with Jewish surnames.  But then about 2 months ago a new match popped up--with the surname Diamond.
The first match is Uncle Leibish's grandson.  The second is this new match
