As Frenda, Frenna and Frendu, we first see this surname documented in Malta on the Militia Roster of 1417.
Potentially a truncated form of the Italian surname Fredesindus, or the Spanish Ferrandu or Ferdinandu. All derive from the Germanic frith(u), meaning “peaceful, friendly”.
Examples of the Frendo coat of arms are extremely hard to come by! Whilst a few variants exist, this version with a dexter arm holding an olive frond over an argent (silver/white) field, all symbols of peace and friendship, seems to be the most traditional.
