Relationship Chart

 
If you have ever wondered about your relationship to a distant cousin, or come across the term "second cousin, once removed", this chart may help to find where they fit into the family.  To start, locate yourself in the chart ("ME") down below.  The diagonal ascending lines are the parents and the diagonal descending lines are the children. For example, if you have the same Great-Great Grandparents as someone, you are 3rd cousins. If your Great Grandfather is his Great Great Great (3 X) Grandfather, you are second cousins, twice removed (2 X). I don't know why, but Uncles and Aunts can be Great but never Grand. 

This chart can be extended to the upper right and lower right as far as desired for whatever degree of cousin you want. I guess eventually we are all related in some way.
