I have scoured Pennsylvania German Pioneers by Strassberger and Hinke looking for any immigrant named Joseph whose surname could possibly be construed as Ditto. The only "Dittos" I have come up with are Abraham Dedie, arrived the Ship, Nancy, in 1754 who it turns out was from Corcelles Moutier, Switzerland, Jean, Jean Pierre and Josue Dedie, who arrived on the ship, Mytrilla in 1765, with a notion, French Swiss Protestants beside their names. Abraham, John Pierre and Jean all had weddings or children's births recorded at Germantown Reformed Church in Lancaster, Co.I have found no information on Josue to date. Nor have I found a Joseph. In any Catholic or Protestant church records.
