Crowl and Grauel are the same family. You can also find it spelled Crowley in later documents. Johann Michael Grauel (b. 1700) is also from Langenselbold and was on the ship "Elizabeth" with our very own Johannas Mohn. His daughter married Vernor Mohn, Johannas' son. I just received some info on Johann Michael Grauel but it seems to concentrate on his son Michael Crowl's (b. abt. 1743) line.
