Fribourg - birth - 1606 - Aebischer - source?
Aebischer of Guggisberg BE have been extensively discussed on https://community.familysearch.org/de/discussion/146403/guggisberg-be-marriage-1809-aebischer-stoeckli and https://www.geneal-forum.com/phpbb/phpBB3/viewtopic.php?t=32693. The first mention Aebischer in Guggisberg seems to be the marriage of Hans Äbischer and Anna Zwaalen [Zwahlen] on 02.07.1627 on https://www.query.sta.be.ch/Dateien/18/D94991.pdf#page=147 (depending on your browser you may have to manually navigate to pdf-page 147).
According to https://www.familysearch.org/ark:/61903/2:2:S59T-3RP Hans Aebischer was born 1606 in Fribourg - likely the canton (not the city), where Aebischer is a fairly common name. The year of birth will be a rough estimate, but in the Guggisberg records I have not (yet) found an indication of his origin (Fribourg) nor his father's name (also Hans). Neither the marriage record nor the (first two) baptismal records of his children mention this.
@SharonZParker (or anyone else with information): what is the source for Hans' origin and father's name? Is there a possibiloity to get in touch with the submitter of "HughVonNiederhausern.ged"?
BTW - once you have the Guggisberg church record open anyway, you should have a look at pdf-page 100 as well 😉.
