Susan Cassidy Gair, born in Bishopbriggs, is described by her granddaughter Lynsey Gare as "family-oriented, very hard working and house proud".

The Possil resident loves quiz programs, murder mysteries, and was very excited to receive her letter from the Queen and to be spoiled by her family on the big day.

Much to her joy, the family marked the occasion by getting together for a delicious meal at an Italian restaurant, prior to an even bigger party on Saturday.

Susan received lots of thoughtful gifts from her loved ones, including a special blanket with pictures and the words '100 years loved' on it, a special necklace and a balloon display.

Affectionately referred to as "the Queen of the family", she was overwhelmed by the love and affection.

Lynsey, who lives with her grandmother, said: "I'm really close with her. We always go out for afternoon tea and shopping. She is very funny and has a very good memory.

"My auntie and I live with her. She is always reminding us when we leave the house if we have our keys, phones or purse because we are terrible."

The 100-year-old is in good health, according to her family, and has kept fit by doing housework into her 90s.

She doesn't drink or smoke and likes to read the newspaper daily to keep up-to-date with affairs and keep her mind active.

Recently, she had a few health scares, including catching Covid-19 at age 98 and undergoing hip replacement at age 99, from which she has recovered brilliantly.

Her granddaughter said: "We all got the virus last year as we returned from London but she was totally fine. We were worse off, me and my auntie.

"It was just like a cold.

"In March, she had her operation and she did really well after, was out of the hospital quickly, just about after a week."

Meeting at a dance at age 18, Susan was married to her husband Charles for five decades.

They had a daughter Melissa, two sons John and Charles, four grandchildren Lynsey, Muriel, John and Charles, six great-grandkids and one great-great-grandchild.
