This was one of the first quilts I made - and I had exactly the same question. A pattern develops different names in different regions, plus, the same names get used for a different pattern someplace else. I've heard all the names given here and some I've forgotten. I've even heard it called a tortilla quilt, I guess because of the round pieces which get folded over. After I made my third of fourth quilt, it stopped driving me crazy.
