patrilineal, i.e., passed from the father to his children. Formally, Lithuanian surnames are divided into two groups—Lithuanian and non-Lithuanian ones. Non-Lithuanian surnames are typically of
Slavic origin that currently possess the partially
Lithuanized endings , or for males and their corresponding forms for married and unmarried females. Although some did manage to change their last names during the
interwar period, Lithuanians never underwent such a process on a mass scale. In 2009, the question of Lithuanians being allowed to fully Lithuanize their family names was raised again, but it received little support. but were reserved for the
Lithuanian nobility. They usually derived from
patronymics. The use of family names gradually spread to other social groups: the
townsfolk by the end of the 17th century, then the
peasantry. People from the villages did not have last names until the end of the 18th century. In such cases their village of origin was usually noted in documents. The process ended only in the mid-19th century, and due to the partial
Polonization of society at the time many names were influenced by Polish form of the name. A number of them were identified from historical names of villages, farmsteads, etc., often in plural, named after the founding families, e.g., Darbutas.
