Why attend a FEEFHS conference is not a difficult question to answer. To start with, the core conference is a 3-day workshop, filled with three parallel tracks of classes. In addition to that, there are 2-day pre-conference workshops with the goal of enhancing specific research skills.
The presenters are researchers who know what they are talking about since many of them have been performing genealogical research for decades at an advanced level.
From it's humble beginnings, the Foundation for East European Family History Studies (FEEFHS) has become one of the most outstanding organizations in Eastern European genealogical research.
