Cpl Alford’s niece, Sheila Lane, and great-great niece, Charlotte Morton, also attended the event, hosted by the RAF Medical Reserves, and said they were “proud” to represent their family.
Ms Lane recalls her aunt leaving for Normandy when she was about six years old.
She said: “I remember being at the cinema with my mother when the Pathe video came on screen, and there was my Auntie Lydia.”
“I’m in awe of her,” Ms Morton added.
“Where we had the ceremony you could see on the floor where they’ve engraved the stones – I guess where they parked the planes.
“It was really nice to see actual memories on the site.”
