PYCROFT Page * COUSINS Charts

Consanguinity

... --- These charts are coded such as to show the amount of DNA that one has of their ancestors.
It can be seen from these charts that the maximum useful time span is 5th cousins, (about 200 years) with your (our?) MRCA (Most Recent Common ancestor) being 4xGtGrandparents (GtGtGtGtGrandparents)


For your further reading, interest or intrigue, you might visit these sites. There's plenty abound.

This chart I made up from a published table of numbers.
Here I am attempting to show the range of matching DNA that indicates what level of Cousin we might be.
--* CentiMorgans is a measure of DNA that indicates how much DNA is shared among individuals. This might be very small or made up of lots of segments. It is the total count of cM that makes the determination of Consanguinity.
This chart shows it is not an exact science, or a definite indication of a specific relationship. A particular value can be made up of a range of relationships, (say Half) and this is included in the possibilities.
