LOSS: Rudy Bruynius, and two-year-old daughter McKayla
Rudy Bruynius, 33, and McKayla were enjoying a family holiday in Cornwall when the weather suddenly changed.
They were killed when a large wave swept over them at Fistral beach in Newquay last August.
Mr Bruynius, his wife Lisinda and McKayla, who was strapped into a pushchair, were abruptly hit by a wave before a second, bigger wave, dragged them into the sea.

Mr and Mrs Bruynius were rescued by beach lifeguards and a lifeboat found McKayla a short time later.
Eyewitnesses, who described the waves as being between 8ft and 10ft and getting bigger, alerted the emergency services after hearing screams.
