Gerasimov Family History

Russian, Belorussian, Bulgarian, and Macedonian: patronymic from the personal name Gerasim, Greek Gerasimos (a derivative of geras ‘old age’ or of a homonymous geras ‘honor’).

This was borne by a 5th-century Christian saint venerated in the Eastern Church who was chiefly famous for the devotion he is said to have inspired in a lion from whose paw he extracted a thorn.
