Abstract (English):
A search for asteroid families was performed in the Hungaria group. Proper elements needed for this procedure were calculated by the empirical method using distributions of osculating elements. All, more than 30000 multi-opposition asteroids, discovered in this region to date, were used for this aim. An approach similar to the hierarchical clustering method was applied for the identification of families. As a result, two asteroid families were found: 434 Hungaria and 3854 George. 434 Hungaria family is a well known one, it includes a large fraction of asteroids in this region. A new family 3854 George was identified in the high inclination region $24^{\circ}$–$26^{\circ}$. It is composed by small asteroids with diameters less than 1 km and includes about 400 members now.
