My son is about to marry the cousin of his sister's husband.

First of all your son is not a blood relative of his sister’s husband’s cousin.

So what is the objection? Do you have some other underlying objection to this marriage? Or do you feel the need to explain to anyone and everyone you meet, the distant marital, non-blood, in-law relationship?

Living on the East Coast, I have cousins who live and grew up in California who I haven’t seen or had any contact with since 1976.

Suppose I meet a really great guy who I will choose to call “Fred” and I find out that “Fred” is the cousin of one of my cousin’s in-laws?

I and my family would just introduce him as my fiancé “Fred” and I wouldn’t feel any need to explain the distant non-blood “in-law” relationship to anyone but my closest friends and then only as a “isn’t a small world” sort of strange coincidence sort of thing.

You bring up a good point about west coast and
east coast relatives.

We in fact are delighted about the unions. This
family is well known, thus people around town
sort of have heard about it. So (when asked) we
find ourselves trying to explain the connections.
It’s actually fun and makes for good converstaion.
The quest for a shorter explanation is merely a
friendly exercise.
