I don’t expect to get one definite answer here, but Google can’t give me one either. Some websites say they’re your second cousin, and others say they’re your first cousin once removed. I’m trying to figure out some family tree stuff so I need to know the difference between the (groups of) terms.
Thank you for the description, that actually makes it a lot easier to understand.
So how do you go about combining the two?
For example, my great grandfather’s sister’s grandson was on the USS Thresher when it imploded. What would his relation be to me?
On that note, what do you call your grandparent’s sibling, vs your great grandparent’s sibling, and so on? Again, Google isn’t being very helpful here.
Great grandfather’s sister’s grandson is your second cousin once removed. That guy is the second cousin of one of your parents because they share great grandparents with one of your parents. A grandparent’s sibling is a great aunt or great uncle to you. A great grandparent’s sibling is a great great uncle or great great aunt to you.
Siblings of grandparents are “granties” and “gruncles”
So your first common ancestors are your great great grandparents, so that’s third cousin, and they’re a generation older than you, so once removed. Third cousin once removed.
Grandparents’ siblings are you great aunts/great uncles, additional generations back you add more greats, so great grandparents’ siblings are your great great aunt/uncle. After a while people say “twice great” etc
I believe that the answer is second cousin once removed.
I believe you need to count the distance to the common ancestor from the older generation of the two people being related.
I agree that the first common ancestor is OP’s great-great-grandparent. But only OP’s relation’s great-grandparent. So OP’s parent and OP’s relation are second cousins.
Then the removed takes you down the tree from OP’s parent to OP.
Ah, you’re completely right.
If that person had a kid it’d be your third cousin, but since that person is OP’s parents’ second cousin, they are OP’s second cousin once removed.
Just in case you didn’t know, there is a pretty cool song about this disaster:

Your grandmother’s sister is your grandaunt, and you use grand and great the same way you do for mother/father but with aunt/uncle.
So I think your fourth cousin twice removed was on the Thresher but someone may correct me.
