Naeffenwappen 64x64

Welcome to the website of the Naeff family and relatives

Here you can get information all about the family Naeff, including the history of the Naeffs, their hometown Altstätten SG and of course the Naeffen reunion.



The date for the Naeffenfest 2024 is set: June 21st - 23rd

The Family History as Book

Dear Naeffen-Cousins

At the family reunion one year ago, the journalist Rebekka Haefeli wrote a report about our reunion in the NZZ (Neue Zürcher Zeitung). With that, the idea came up to write a book about the Naeff family. Ronja Sakata and Andreas Müller took on the idea together with Rebekka Haefeli and created a first draft of the idea. The Naeffenfest committee discussed the proposal at the closing meeting of the reunion 2019 (see attachment - german only). The idea got positive feedback. The comittee commissioned the initiators to invite historically interested family members to join the project. Naturally, the question about the projects financial aspect was discussed as well.

The initiators of the project were asked to present a budget which shows the financial possibilities and a time plan. The desirable timeline plans the publication for the next reunion in 2024.

For now, we would like to present the ideas to you and ask if you would like to join this project. We would be very interested in your comments, recommendations and criticism. Aside from collecting documents and images, we need IT specialists which can help to bring the files into electronically readable form. A chapter should also show how our relatives abroad live. Who would like to participate in that? At the beginning of our work we will also examine all existing documents which have been collected by Laurenz Gsell and Renate Altwegg-Im Hof.

Mit herzlichen Naeffengrüssen
