Surnames Including Collateral Branches - Updated

Back in 2009 I exported a list of surnames from my database, and calculated the frequency of each using this Word Frequency Counter.

Here's an updated list of surnames with counts greater than 10

217 (C/K)R(U/OO/I)V(A/O)N(T/D) This surname has as many variant spellings as one can imagine phonetically. KRUVAND, KRUVANT, and CRUVANT are the three most common.
