 Also you can use splitter directly by calling module function FullNameSplitter::split
 
     FullNameSplitter.split("Juan Martín de la Cruz Gómez")  # => ["Juan Martín", "de la Cruz Gómez"]
-    FullNameSplitter.split("Ludwig Mies van der Rohe")      # => ["Ludwig", "Mies van der Rohe"]

+If the lib can't split a name correctly, it is possible to split by comma

+    FullNameSplitter.split("John Quincy Adams")   # => ["John Quincy", "Adams"]
