Consanguinity

From open-encyclopedia.com - the free encyclopedia.

Consanguinity, literally meaning common blood, describes a family relationship between two individuals. A consanguinity chart (or table), as seen below, is often used to illustrate that relationship.

In the Catholic Church, a marriage with a direct line relative or collateral relative to the fourth degree is grounds for an annulment. In other words, you could not marry your 1st cousin (4th degree), grand nephew/niece (4th degree), but you could marry your 1st cousin once removed (5th degree).

The succession law known as consanguinity, requires that the next monarch be of the same blood of the previous monarch; allowing, for example, illegitimate children to inherit.
