i was quite surprised to find myself over this familiar territory :)
What kind of uncle am I?
Like every language, English has its own collection of words to express family relationships. There are the easy ones like mother, father, brother, and sister. Also comparatively easy are cousin, aunt, uncle, niece and nephew. But most people don't know about this "removal" part, beyond the fact that your "first cousin twice removed" is somebody you probably met once at a wedding ten years ago.
It's really not that complicated. Some people think removal has to do with estrangement, but actually it has to do with generations. The children of your Nth cousin are your Nth cousins once removed. Their grandchildren are your Nth cousins twice removed. In general, to find your Nth cousin K times removed, go to your Nth cousin and then follow their children K times.
You can also look at it from the point of view of the younger relative: Your Nth cousin K times removed is the Nth cousin of your Kth direct ancestor, where K = 1 is your parent, K = 2 is your grandparent, etc. For example, your father's second cousin is your second cousin once removed. There's a nice chart at genealogy.com that depicts many of these more complicated relationship terms.
