My services

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

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 training at the Ecole Nationale des Chartes and the Institut Français de Formation à la Généalogie, and especially by multiplying investigations and solving complex cases.

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 when necessary with colleagues of the UPro-G network (Union Professionnelle de Généalogistes) of which I am a board member.

Family history in France or Germany

Here are my most common areas of intervention 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, 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.


Speaker during fairs or for associations or companies


Genetic genealogy workshops

« Sonder le passé pour éclairer le présent, passionné et professionnel, Greg Wolf est la personne idéale pour nous accompagner dans nos recherches. Un vrai détective, grâce à lui j’ai retrouvé mon AGM décédée en 1934 aux archives hospitalières et un dossier d’enfant assisté. Je fais régulièrement appel à lui dès que je bloque dans mon arbre. Efficace et passionnant. Merci Monsieur Wolf »

« J’ai fait appel à Greg Wolf pour m’aider à rechercher les parents d’un ancêtre abandonné. Il m’a permis d’avancer à la fois dans la construction de mon arbre généalogique en trouvant des archives utiles dont j’ignorais l’existence (en particulier des dossiers de naturalisation) et dans l’interprétation des correspondances ADN que je ne savais pas exploiter. Merci de m’avoir accompagnée avec bienveillance et efficacité dans la résolution de l’énigme généalogique de mon histoire, bloquée depuis un certain temps. »

« Greg Wolf a reconstitué mon arbre généalogique et retrouvé l’ensemble de mes ancêtres sur 6 générations dans les départements du Rhône, de la Loire, de l’Isère, du Lot et de l’Ardèche. Il a déniché des actes qui m’ont permis de mieux comprendre la vie de mes ancêtres, d’avoir fait la lumière sur certaines histoires de ma famille. Et grâce au test ADN il a pu retrouver mon arrière grand-père biologique . J’ai eu l’éclairage sur certains non-dits. Merci »
