Nagalova
Nagalova is a surname of Slavic origin. While not exceedingly common, the name is found primarily in Russia. Genealogical records suggest the name may be associated with locations or ancestral professions, but detailed etymological information is limited. Further research into Russian onomastics would be necessary to determine a precise origin and meaning. The surname is likely a patronymic, meaning it was derived from a male ancestor's given name or nickname, but without additional context, the root name remains speculative.
