Talk:List of coupled cousins/workspace
![]() | This is not a Wikipedia article: This is a workpage, a collection of material and work in progress that may or may not be incorporated into an article. It should not necessarily be considered factual or authoritative. |
List of marriages between remote relatives (1st cousins once removed, 2nd cousins, or more remote). Cut from article as irrelevant.
First cousins once removed have a coefficient of relationship of r=6.25% (1/16). Half-first cousins also have r=6.25%. Second cousins have r=3.1% (1/32), third cousins have r=0.8%, fourth cousins have r=0.2%.
People with a coefficient of relationship below 0.1% (half-fourth cousins and more remote) usually do not have a closer genetic relationship than with the average person from their population, and cannot be readily identified by genetic testing.[1]
Royalty
[edit]Europe
[edit]The royal couples listed here are but a small representation of the innumerable cousins of varying degrees who have married between royal or noble houses. Due to the constitutional interest that their marital status raises, as well as the fact that genealogical records of royal houses are more plentiful and readily available than those of ordinary people, their bloodlines are better known than those of commoners.
