I apologize for (1) the second post which was inadvertant as I am just learning how to use the website and (2) for my awkward use of language. What I meant was is there an English word that expresses the same relationship as the Yiddish word machatanim. My wife and I decided to invent one and started to use "marrakin" as in kinship through marriage, but not as in-laws. Any more suggestions?
