In 1609, all families in Einsiedeln obtained a Stamm-Number. The Kalin Clan, whose numbers consist of 48 lines, obtained the numbers 78 through 120.
This name originated in the town of Einsiedeln, Canton Schwyz, Switzerland. Kaelins make up about one-third of the names, and is the largest surname group in the town.
I have collected quite a lot of information about Kaelins from Philadelphia and the surrounding area. Some I have been able to connect to my line, but most I have not. The information is widely varied and does include a few photographs.
It is my understanding that the Kaelin name, in it's original spelling of "Kälin", holds Swiss Citizenship prior to 1800.
