By presenting new compound personal names given to Lithuanian citizens born in the period 1991–2010, the article discusses one of the ways used to update the Lithuanian stock of proper names in the recent decades. The study revealed that compound proper names are created by combining commonplace stems with new components which mostly originate from appellatives (or names of appellative origin), hypocoristic compound personal names or foreign names which are the most common base words. They show that the meaning of the base word is not important in the formation of the stem of a proper name. There are also proper names composed of two new stems, which testify the tendency to create personal names with a single new stem. The proper names under analysis make it clear that the main reason behind the creation of a new name component is the popularity or frequency of the personal name which has it; it was also supported by the selection of traditional stems for the creation of new proper names. The most common base of stems is the first syllable and the first consonant of the second syllable, which shows that as the part of the word is turning into a stem, the beginning, being its most important meaningful part, usually surpasses the limits of the syllable.
