I have German relatives (probably Palatinates) who immigrated through Philadelphia and settled in Westmoreland County. Very little documentation about these people is in public record. This note is an invitation to others researching this space to contact me so we can share what may exist in private records.
The Lauffer family is well documented on their family web site. It connects to the Bash family when Magdalena marries Johan Martin Bash Jr., also a second generation immigrant (born in the US to a father born in Germany).
