Mary Troyer Strain the mother of these four beautiful children is my cousin-once-removed.
These three women represent three generations. So they are not cousins. One of these ladies sort of thinks a-cousin-once-removed ought to be a deceased cousin.
I Googled Cousin Once Removed and this is the definition.
(So your first cousin once removed is the child (or parent) of your first cousin. Your second cousin once removed is the child (or parent) of your second cousin. And your first cousin twice removed is the grandchild (or grandparent) of your first cousin.)
