Matriname

A matrilineal surname or matriname is a family name inherited from one's mother, and maternal grandmother, and so on whose line of descent is called a mother-line, mitochondrial line, or matriline. A matriname passed on to subsequent issue is unchanged, as compared to a matronymic, which is derived from the first name of each new mother.

The term "matriname" was introduced by Prof. Bryan Sykes in his book The Seven Daughters of Eve, stating that "We would then all have three names: a first name, a surname and a new one, a matriname perhaps."

The mitochondrial DNA (mtDNA) is inherited by biological motherhood whereas the matriname can be equally given after adoption or surrogacy.
