"If your cousin has a child, that child is a FIRST COUSIN ONCE REMOVED to you, i.e. one generation removed from being a first cousin.
If you have a child, your child is a SECOND COUSIN to your first cousin's child.
If your first cousin has a grandchild, that grandchild is a FIRST COUSIN TWICE REMOVED to you, and a THIRD COUSIN to your grandchild.
It keeps working the same way. If you find a 12th Cousin somewhere, their grandchild would be a TWELFTH COUSIN TWICE REMOVED to you.

The ggCHILD on the left (above) is a SECOND COUSIN TWICE REMOVED to the g3gCHILD on the right (above). (NOTE: The g3gCHILD on the right IS NOT a Fourth Cousin Twice Removed to the ggCHILD on the left; the relationship is still 2C2R.)

So the Cousin rule-of-thumb is, the "great"s are always one less than the cousin relationship.
The above method of determining relationship is:
There is another method used by some people that refers to a 1C1R as a 2C; a 1C2R as a 3C; a 1C3R as a 4C; etc. This is likely why there is so much confusion on the issue of cousins and removed.
The word "Half" means only one of two parents is the blood parent, so where two siblings share only one parent, they are half-siblings. The children of these two half-siblings would be half-cousins, because they share only one of the grandparents.
So, half-cousins are called that, because they share only one of the two grandparents commonly. As far as Half-Cousin and Removed is concerned, the same rules apply as to full cousins.
Double Cousins are the result when two brothers marry two sisters (of another family). The children of each married pair are cousins to each other, not only by way of their father's family, but by way of their mother's family as well.
Otherwise, the same rules apply as to full cousins; so one (whose grandparents were brothers who married sisters) could have a SECOND DOUBLE COUSIN ONCE REMOVED.
Marriage between COUSINS:
Most of us in the USA have at least one case of first cousin marriages somewhere in our ancestry. In some cases, it was due to the relatively small populations of newly settled areas - where there was not much other choice for marriage partners.
It must be noted here that first-cousin marriage taboos are pretty much restricted to North America. In fact, about half of the states in the USA allow first-cousin marriage."
We have two of those in our own family, and they both worked out well, resulting in both cases in lifetimes of happiness. They all had ten figures and ten toes and no abnormalities at all, said a cousin, who grew up in their midst.
