Richard W Davis, Springville, Utah, researched these famlies. He stated:
'These books are an attempt to establish a link between the known Anabaptist
families in Switzerland and Germany in the 1600's and 1700's and the
Anabaptist families who arrived in Pennsylvania between 1709 and 1776.'
"Between October 16, 1671 and December 14, 1671, 643 Mennonite refugees
had arrived in the Pfalz, mostly from the Emmenthal Valley. There were
100 refugees who had recently arrived in Alsace and who would be coming
to the Pfalz in the spring. This made a total of 743 people, probably
the largest group of Mennonite refugees to be driven from Switzerland
at one time. Throughout the history of the Anabaptists, they traveled
together whenever they moved to a new area."
