There were cases of men who married women from Rabbinical lineage and
took the wife's maiden name as their family names. One example is the
son of a Rabbi David, Rav of Novarodok who married a HOROWITZ (from
Minsk) and he adopted her family name due to its famed rabbinical
lineage. This is a case in which a HOROWITZ was not a levite (Levi) as
are almost all of the HOROWITZ clan. Of course all their male
descendants will not levites .
