Consanguinity

Property of being from the same kinship as another person

Consanguinity (from Latin cōnsanguinitās 'blood relationship, kinship') is the characteristic of having a kinship with a relative who is descended from a common ancestor. Many jurisdictions have laws prohibiting people who are closely related by blood from marrying or having sexual relations with each other. The degree of consanguinity that gives rise to this prohibition varies from place to place.
