The Loncharich surname is an occupational name of Croatian origin and includes variations of Loncar, Lonchar, Loncaric, Loncarich, and Loncharich and other spelling variations. The family name appears in Europe, Canada, USA and South America. One of the earliest references to the Loncaric name is a record of one Djordj Loncaric, who was ennobled and granted a coat of arms by the Austrian Empire in 1747. The honor was registered later that year with the Croatian assembly. This DNA project represents the first time various Loncharich families have attempted to establish connections between family lines. To participate meaningfully, test subjects will need to provide their direct male line ancestry back to the earliest known Loncaric (or variant) either in the form of a pedigree chart or, preferable, family group sheets (excluding living persons).
