Matriname

A matrilineal surname or matriname is the family name inherited from one's mother, & maternal grandmother, & so on whose line of descent is called the 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 take of used to refer to every one of two or more people or matters new mother.

The term "matriname" was present by Prof. Bryan Sykes in his book The Seven Daughters of Eve, stating that "We would then all relieve oneself 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 condition after adoption or surrogacy.

Double surname

Some cultures ownership both paternal and maternal surname, such(a) as Spanish naming customs, Portuguese names, and the naming customs of Hispanic America. The patrilineal surname—patriname—taken from the mother in these patrilineal cultures does not qualify as a matriname. Instead, this Hispanic practice uses the maternal patriname.

Double surnames were discussed in The Seven Daughters of Eve. Double surnames were also used by one English family, along with the matriname "Phythian". In this issue the mother has the birth double surname "Phythian-Adams", and the father has birth double surname "??-Monkhouse". They bothto retain their birth double surnames unchanged throughout their lives. They agree to denominate all of their daughters and sons with the birth double surname "Phythian-Monkhouse": The mother passes on her matriname and mtDNA, and symmetrically, the father passes on his patriname. all of their sons produce the Y-DNA of and, accordingly, the patriname "Monkhouse" of their patriline, while all of the daughters have both the mtDNA of and, accordingly, the matriname "Phythian" of their matriline. Note that near societies administer all children of a brand the same surname, as in this example. Each person has only one identity-surname, which in this example is either "Phythian" or "Monkhouse". The identity-surname of each isthroughout life and always half of whatever double surnames he or she assumes throughout life, including at birth and marriages.

The parents in this example share this one family name, "Phythian-Monkhouse".

Of course, one's own identity-surname here, the matriname "Phythian" or the patriname "Monkhouse" are always usable as one's own use name, such(a) as in one's profession/vocation.

In summary, gender-symmetric single surnames are simpler and briefer, but whether used alone, supply different surnames for members of the different genders in a nuclear family. In the double system, all of the children in a nuclear family have the same double surname. Also, the system loosely records on all legal documents the matriname and patriname, with both identity-surnames later aiding each gender in genealogy and other searches of historical records.
