I had heard that a similar story happened amongst the Belz community in Yerushalayim.
The Story story goes like this:
Boy wants to marry girl.
Girl’s family has boy over for a shabbos meal (with girl not at meal).
Mother not happy with the way the boy eats, tells girl not to marry him.
Boy and girl get married to other people, each have kids.
Later on both boy and girl divorce, eventually marry each other.
Kid from boy’s original marriage then marries kid for girl’s first marriage.
(Belz later forbids bringing over potential shidduchs for shabbos meals, seriously)
I heard this from a family with a REAL connection connection to Belz and the Rebbe.
