Thanks for the journey through all of the possible quilt block names. My first thought was the block was a variation of the Mexican Star. It is only the center "X" without the pieces that make up the secondary pattern. What fun you will have when you actually get the blocks in hand and can see and feel the blocks.
Now, this is just a random thought......You may want to consider gently washing the blocks. The blocks may shrink or may not shrink evenly. That could impact how you cut down the blocks. Perhaps try washing just one block to check for shrinkage.
Let your adventure begin!
