I have a book called 849 TRADITIONAL PATCHWORK PATTERNS A PICTORIAL HANDBOOK written by Susan Winter Mills
It has the picture of the pattern block and a list of different names that block has been called. Some have as many as two different names and some up too as many as seven or eight different names and variations of that same block. I agree with Shemjo. Different people have come up with that idea in different places and thinking that it is theirs have given it a name!!
