The body of 50-year-old Juan Bedoya López was found on the shore near the A Frouxeira lighthouse in Spain's Galicia province, local daily La Voz de Galicia reported on Tuesday.
Bedoya, a local butcher, was one of four members of the same family swept away by a massive wave which struck the rocky shoreline of Valdoviño.
Witnesses said a pair of waves struck the lighthouse of Meirás where the family had gathered at sunset.
The man's son and elderly brother-in-law are still missing while his daughter managed to make her way back to shore.
In a tragic turn of events, the family had gathered to sit with the ashes of Bedoya's father who died a month ago.
Rescue workers are now continuing their search for the other missing family members, but local mayor José Antonio Vigo Lago said poor weather conditions were hampering those efforts.
Waves of up to 10 metres in the region were reported as wild weather battered Spain's Atlantic coastline.
