A Rominche is considered as such by reference to parentage—that is, at least one parent must be Rominche. "Didikois" is the usual term applied to "half-breeds," while non-Rominche are called "Gorgios." Kinship is recognized bilaterally, but it is usually reckoned rather shallowly: for most purposes, only the grandparental through grandchild generations are counted. First, and possibly second, cousins are considered too closely related for marriage. One's recognized circle of kin have moral obligations to provide assistance and loyalty in times of trouble. Naming practices are used to emphasize personal associations—for example, a woman can elect upon marriage to retain her father's name, to take on her husband's name, or to reject both in favor of her mother's surname.
