Oldest active genealogy office in Switzerland

Aicher, Nobs & Partner GmbH (formerly Büro Aicher) combines over three decades of genealogical and probate research with a modern, international network. We specialise in turning complex historical records into clear, documented results that private clients, heirs, and institutions can trust.

Founded as the successor to Büro Aicher, our firm has grown from a pioneering Swiss genealogy office into a specialised provider of genealogy and probate research with a focus on German-speaking regions. With more than 30 years of continuous practice, we are frequently recommended by archives and institutions for clients who require professional help with lineage reconstruction or heir searches.

Guided by evidence standards, legal frameworks, and ethical practice

Our research is driven by a simple principle: conclusions must be understandable and verifiable by others. We rely on church books, civil registries, archival files, and other primary sources, citing every key step so results remain transparent and defensible. This approach serves both private clients who want a trustworthy family history and professionals who must meet formal standards.

Proof-first methodology

We build conclusions on documented sources and a clear evidence trail, so results remain traceable, defensible, and usable for real decisions.

Documentation aligned to probate requirements

Heir tracing and inheritance proof depend on the right records. We obtain and compile the necessary documentation in a structured way that supports probate processes and statutory inheritance rules.

Discreet, risk-aligned representation

We handle sensitive family matters with discretion. For represented heirs, there is no upfront payment and fees apply only if an inheritance is paid out—keeping incentives aligned and financial risk controlled.

We turn complex historical records into verifiable proof—so families, institutions, and heirs can move forward with clarity in genealogy and probate matters.

Global support in 100+ countries through the Historikerkanzlei Network

We work with correspondents in Afghanistan, Albania, Algeria, Andorra, Antigua and Barbuda, Argentina, Australia, Belarus, Belgium, Bolivia, Brazil, Bulgaria, Canada, the Caribbean, Chile, China, Colombia, Cyprus, Denmark, Ecuador, Estonia, Finland, France, French Guiana, Georgia, Greece, Iceland, India, Indonesia, Iraq, Iran, Ireland, Israel, Italy, Jamaica, Japan, Lithuania, Latvia, Luxembourg, Malta, Mexico, Moldova, Monaco, Namibia, Netherlands, New Zealand, Norway, Paraguay, Peru, Philippines, Poland, Portugal, Russia, San Marino, Scotland, Slovakia, Spain, South Africa, Sweden, Switzerland, Thailand, Czech Republic, Tunisia, Turkey, Ukraine, United Kingdom, Uruguay, USA, Vatican, Venezuela, and Vietnam.
