While Karl Porath is not my ancestor, his family married into the Boyle family, so some of my Boyle-descended cousins are also descended from Karl and Caroline Porath.
The relatively sparse surname wordle to the left would indicate that I have very little detail about this family. That is correct.
There is more information about this family in the booklet "Do You Mind The Time, When ... ?" (1.7 Mb, PDF format).
