Third cousin 6 times removed
A third cousin 6 times removed is a relative of your own generation line, and the word works both ways: you are their third cousin 6 times removed too.
The route
Red line: from you (4 steps up) and 10 steps down. Gold: the shared ancestor.
How to count it
Go up from you to the nearest ancestor you share with the other person. That takes 4 steps for you and 10 for them.
The smaller of the two, minus one, gives the degree: 3rd cousin. The two numbers differ by 6, so the cousins are 6 times removed.
Cousin counting is the standard genealogical convention. Different families and legal systems sometimes use looser words, so check the naming conventions guide if a relative uses a different term.

Full and half
The figures above assume full relatives, who share a couple as common ancestors. If the link runs through just one person, because of a remarriage or a different other parent, the relationship is a half relationship. It is usually written half third cousin 6 times removed, and the average shared DNA falls to 0.0061%. See full and half relatives.
The DNA numbers are theoretical averages. Real amounts vary a lot from one pair to the next, especially for distant cousins, so read the DNA guide before comparing against a test.
