In Seminary a teacher of mine came to school excitedly saying her grandmother was engaged.
I believe the couple were in their 60’s or 70’s,
She showed us a picture, it was hysterical, they looked so cute.
I know of another 2 couples.
Doesn’t make headlines unless your famous.
Just like any other shidduch won’t make headlines unless your famous or there’s something really special and unique about it, the idea of people finding their second zivug in their older years is baruch hashem not unique, that’s why it’s not publicly announced all the time. It is uncommon though, so in the cases I’ve heard, most of the neighborhood/city knows and becomes involved in the chasuna and preparations. Still, not uncommon enough to make newspapers.
