The name Chamorro may be both a patronym and a matronym. In Spanish speaking countries, the patronym is usually followed by the matronym to more precisely identify an individual (See Iberian naming customs). In English speaking countries, the matronym is frequently omitted, resulting in ambiguity. Omission of a given second or middle name further obfuscates an individual's identity.

• Pedro José Chamorro Argüello, first politically active member of the Chamorro family
