Tadej Trnovšek researching ancestral houses - Explore the heritage of Genealogy Slovenia's founder

Why Work With Me

If you are searching for reliable archival research in Slovenia and the former territories of the Austrian Empire, I can help you navigate both historical archives and modern genealogical resources with clarity and precision. My work combines direct on-site access to national, regional, diocesan, and parish archives with systematic research in trusted online archival and genealogical databases.

I regularly work with parish registers, manorial and estate records, land documentation, civil records, and early modern sources that are often unavailable outside Slovenia. Whether you are tracing your ancestry, resolving a complex lineage question, or gathering documentation for legal or citizenship purposes, I approach each project with methodological rigor and historical understanding.

My background as a historian and former senior curator has shaped the way I work. I do not simply collect names and dates. I analyze sources critically, evaluate evidence carefully, and place each family within its proper historical and social context. This ensures that your family history is not only accurate, but meaningful.

I am a Member of the Association of Professional Genealogists and a member of the Slovenian Genealogical Society, committed to professional standards, ethical practice, and continuous education in genealogical research.

Beyond Names and Dates


Genealogical research is not limited to collecting names and dates. Each document reflects the legal, social, and economic structures of its time. To understand a family’s past accurately, records must be interpreted within their historical framework rather than treated as isolated entries.


In my work, I examine parish registers, manorial and estate records, land documentation, civil registers, court materials, and early modern manorial records as interconnected sources of evidence. By analyzing how these documents relate to one another across generations, it becomes possible to reconstruct family structures, property relations, social status, and patterns of migration with greater precision.

This method ensures that research is not only factually accurate but also historically grounded. The result is more than a lineage chart: it is a documented and coherent account of your family’s place within its broader historical context.

Professional Background


My professional path is rooted in academic training and long-term work with historical sources. I hold Master’s degrees in History and Cultural Sociology from the Faculty of Arts, University of Ljubljana, where I developed a strong foundation in historical methodology, source criticism, and social analysis.


For sixteen years, I worked as a curator and later Senior Curator at the Slovene Museum of Christianity. My work involved research in early modern manuscripts, ecclesiastical archives, and complex historical collections, requiring careful interpretation of primary sources and critical evaluation of documentary evidence.

I am the author of the 530-page scholarly monograph Stiški urbarji iz 16. stoletja (2017), a critical edition and transcription of sixteenth-century manorial records of the Cistercian Abbey of Stična. This work reflects my long-term engagement with archival material and contributes to the study of early surname development and regional history in Central Slovenia.

Personal Note

Genealogical research is, for me, more than a profession. It is a long-term commitment to understanding how individual lives are shaped by historical circumstances and how family stories connect across generations. I approach each project with patience, discretion, and respect for the personal significance that family history carries.


Whether you are seeking answers about your ancestry, clarifying complex lineage questions, or preparing documentation for official purposes, I strive to offer careful guidance and reliable research grounded in both archival expertise and human understanding.
