Jeff, My grandfather was Charles ROCK, son of Herman ROCK and Wilhelmine/Minnie SCHINKE/SCHUENKE. He was born in Clintonville, Waupaca Co. in 1874. His brother William/Bill was born in Loepersdorf, Kreis Reginwalde, Prussia as was his sister ANNA. I believe the town Joseph BAYER was from was Pesthigo which is in Marinette Co. I am sorry I do not have much more information than that for you. Patti in WA state
