NAMES OF EARLY SETTLERS IN TULPEHOCKEN, BERKS AND LEBANON COUNTIES. — As early as 1723, thirty-three families of Germans, who had come to New York 1710, settled in Schoharie 1713, left there and located on Tulpehocken Creek; among these were... In 1728, others from Schoharie settled here... Andreas Kapp...
p. 466	The first settlers in Tulpehocken were Lutherans and German Reformed.  Rev. Tobias Wagner was the first pastor of the Lutheran Congregation.  The following is a List of the members of the Tulpehocken Church, from 1743 to 1746: Friederick Kapp, Andreas Kapp...

The big question is:  Is the Andrew KAPP who came to Tulpehocken in 1728 the same one who appears there in the 1740s?  The five KAPPs in Tulpehocken in the 1740s are considered to be brothers ("Cass" is obviously a misreading of "Cap"), who immigrated to Pennsylvania in the 1730s.  So if, as it seem probable, these are two different Andrew KAPPs, how does the one from New York relate, if at all, to the ones there in the 1740s?  And, in any case, how are we going to separate their children?!
