Glyn's family came from Groeslon, near Caernarfon, but he was born in Bolton after his father moved to Lancashire to find work. Glyn briefly attended Groeslon primary school, and his widow Carrie recalls: "One lady who was in school with Glyn says he used to put frogspawn down her back - though he always denied it! I think he was a bit of a naughty little choirboy there."
After the death of his aunt Jane in 1987, Glyn and Carrie returned to live in the family cottage in Groeslon. "Although he was very much an actor and mates with all the London crowd, he loved coming back to north Wales. He adored walking and practically camped out on the beach with our German shepherd, Ianto," Carrie said.
Glyn acted alongside many of the greats. Carrie recalls: "We did an evening of Dylan Thomas with Richard Burton, Ruth and Philip Madoc, Hywel Bennett and Gareth Rees. Afterwards we went for drinks and Richard Burton was there with Elizabeth Taylor. As they walked past our table Richard Burton said, 'don't drink too much'. Well, that was the pot calling the kettle black! I think he was referring to their trips to Cardiff to watch Wales play rugby."
In a career spanning almost 50 years, Glyn was most famous for his role as gruff boatyard owner Jack Rolfe in the BBC TV series Howard's Way. He was also in programmes such as Doctor Who, Emergency Ward 10, Coronation Street, Peak Practice and Heartbeat.
On the stage he played Claudius in Hamlet with Tom Courtenay, appeared on Broadway with the Royal Shakespeare Company and at Drury Lane with Harry Secombe in The Four Musketeers.
Both Glyn's children, Lloyd and Cathy, are actors. Lloyd found fame playing Paul in Monarch of The Glen and has recently been recording a new drama series in Manchester for the BBC. Cathy divides her time between London and America, returning each summer to work with the National Youth Theatre.
Glyn died in 2004 and is buried with other members of his family in Groeslon. Carrie, who is a volunteer at Theatr Colwyn, was among the first batch of supporters to sponsor a seat in the Colwyn Bay theatre's auditorium. The seat is dedicated to 'a great actor'.
Carrie explained: "Glyn took me to a variety evening with Ivor Emmanuel at Theatr Colwyn in the 1980s and we stayed behind for over two hours, having a great time with him. I've loved that little theatre ever since and it would be a tragedy if it ever closed, so I do all I can to support it."
