いとこ婚
Chhantyals are formed of twelve different clans which are as follow: Bhalanja [भलंजा], Budhathoki [बुढाथोकी, Dandamare [डांडामारे], Gharabja [घरब्जा], Gharti [घर्ती], Gyapchan [घ्याप्चन], Jhingraja [झिङराजा], Khadka [खड्का], Potlange [पोट्लाङ्गे], Purane [पुराने], Singe [सिङे], and Tathapja [तथप्जा].Traditionally they marry inside their twelve clans. One of the major distinct characteristics of the community is the marriage tradition. Cousin marriage is allowed but has to be outside one's own clan.
