From "Hasidism in Israel", by Tzvi Rabinowicz. In describing a marriage between first cousins:
"thus, the houses of Halberstam and Teitelbaum were once again united."
Brilliant, Tzvi. I should use that technique when I explain the various incestuous relationships I've found in my family tree to my horrified relatives. (It's one of the most fun parts of genealogy work.)
