To answer that question, I've recruited my second cousin, Pat Rowell to be our example...
|My 2nd cousin, Patricia "Pat" (Gowland) Rowell.|
Pat's grandmother (Hulda May Culbert) and my grandfather (Myron Manford Culbert) were brother and sister.
Now, think about your own situation. Do you know someone who is the great-grandson or great-granddaughter of your great-grandparents? (Aside from your siblings, of course.) Then that person is your second cousin.
So what about the child of your second cousin? I'm glad you asked. Introducing Jeff Rowell, the son of my second cousin, Pat Rowell...
Try to guess.
A round of applause for those who've figured it out.
Jeff Rowell is my second cousin, once removed. "Once removed" means there is a difference of one generation separating us. If you've been reading the Culbert Family History blog since the beginning, you already know about first cousins, once removed.
So now you know! Go forth and impress your friends with your new-found knowledge.
