I am looking at a marriage record for 1723 from the Reformed church in the town of Markirch in Alsace, where many Swiss and people of Swiss descent were baptized and married. In this record, the groom, Peter Bruegger (Junior), is identified as the son of a Pete rBruegger (Senior) who is deceased, but was a "burger"? from Schwarzenburg. I looked at the records for Schwarzenburg/Wahlern, but could find no mention of a Bruegger who was married there in the 1680s or 1690s. I know for a fact that Peter Bruegger Jr was born in Alsace to Peter Bruegger Sr in 1698. My question: if Peter Bruegger Sr was also born outside of Schwarzenburg, but had been registered by his own father (who ever that may have been) as a citizen of Schwarzenburg, could Peter Bruegger Sr himself later register his own son Peter Bruegger Jr as a citizen of that Swiss town as well? In other words, is there a general rule of thumb for how many generations a family could have kept registering children born outside of Switzerland as citizens of a town there? Thanks, Dale Bricker
