My services

I am a professional genealogist who combines two complementary skills, family history and genetic genealogy. After more than 30 years of personal research on my family as a passionate amateur, I have professionalized my practice by following the trainings of the Ecole Nationale des Chartes and the Institut Français de Formation à la Généalogie, and especially by multiplying investigations and complex cases.

You need help to trace the genealogy of your ancestors who emigrated from France or Germany, publish your research in a book or on a website, understand the results of your DNA test or identify an unknown ancestor? Contact me at !

Whether you don’t have the time, the desire or the skills to do your research by yourself, I analyze the feasibility of your request, and offer you an hourly or flat-rate estimate depending on the complexity of the service and possible travel.

Being based in Paris, I can quickly carry out your research in the main archives of Ile-de-France (Archives de Paris, Archives Nationales in the Marais and in Pierrefitte, Service Historique de la Défense in Vincennes, etc.). And my area of intervention is much wider: because of my origins, I specialize in the archives of the Grand Est (Lorraine and Alsace) and German-speaking countries (Germany, Switzerland, Austria, Belgium, Luxembourg), and the British branch of my wife’s family has led me to further expand my research territory internationally (United Kingdom, Ireland, Sweden, United States, etc.). I also work as soon as necessary with colleagues of the UPro-G network (Union Professionnelle de Généalogistes) of which I am a member.

Family history

Here are my most common interventions in family genealogy, knowing that I also perform more personalized services. I take particular care in the writing and visual rendering of my research reports, which systematically include a detailed account of my approach and all the records found.

Ascending genealogy

Research and design of your family tree over 5 or 6 generations or more

Descending genealogy

Search for all the descendants of a couple of ancestors


Ad hoc research to solve your genealogical brick wall

Military genealogy

Research of documents and reconstitution of military history

Land genealogy

History of a property, its owners and its successive inhabitants


Deciphering and transcribing ancient documents in French, Latin, German and English

Genetic genealogy

Genetic genealogy is a new discipline that I have already mastered perfectly, having participated in many international conferences on the subject.  If you have done a DNA test, I can help you understand and exploit the results you have obtained: interpretation of the report provided by the laboratory, analysis of genetic matches, search for biological relatives or unknown ancestors, individual coaching on your research, etc.

Results analysis

Interpretation of your DNA test results and action plan

Genetic tree

Search for biological relatives or unknown ancestors


Follow-up of the evolution of your genetic matches in each laboratory

Conferences and training

Finally, I like to share my knowledge and passion with amateur and professional genealogists. I regularly give lectures for associations or institutions, or at genealogical fairs, either in person or remotely. I actively monitor new tools and innovative features in genetic genealogy to integrate them into my lectures.
