I use this simple way to remember:
First cousins share Grandparents
Second cousins share Great Grandparents
Third cousins share Great Great Grand parents
Fourth cousins share 3x Great Grand parents etc.
For times removed count the generations from the above
e.g. My father's first cousin is my first cousin once removed
His second cousin is my second cousin once removed
My Grandfathers first cousin is my first cousin twice removed etc.
