I, too, am a Rey from Switzerland.My family came to America in 1850 from Fahrwangen, Kt. Aargau. My great-great grandfather was Rudolf Rey(1811-?).He brought with him his 2nd wife(Anna Dobeli) and his two sons Rudolf(1836-1914) and Samuel(1838-1907) as well as Anna's son(Jakob Rey 1839-1888).I am descended from Samuel.Rudolf and Jakob eventually returned to Switzerland.I can go back to 1745.Also I have records of the first Reys von Fahrwangen in 1340 and can go from there to 1531.I am seeking information to close the gap.According to the Staatsarchivar des Kt. Aargau are family orginall came fromthe region of Buttwil on top of the mountain Lindenberg, 4 miles southeast of Fahrwangen.
I look forward to hearing from you.Also, one branch was at Aesch, Kt. Luzern by 1400-1438.The name mentioned is Hentzman Rey or Reig.Tom Rey
