This month, Ms Newton celebrated her 104th birthday at her Northamptonshire care home.
She was joined by staff, residents and family at Lancum House in Wellingborough to mark the amazing milestone with a buffet and birthday cake.
Leading the celebrations was local singer Karl Richardson, who regularly entertains the residents at Lancum House and other Shaw healthcare care homes.
Born in Irthlingborough, Northamptonshire, Kath met and married Archibald Newton. The couple lived in Finedon and had three children.
Archibald sadly passed away when Kath was only 47 and she continued to raise the children alone. Later in life, Kath became a waitress and continued to work until the age of 75.
Lancum House manager Yvonne Murphy said: “Kath is a delight and all of us at Lancum House love to listen to her stories. I am so pleased that we were able to share this wonderful milestone with her and help her celebrate.”
When asked what her secret to a long life was, Kath, who has lived at the home for more than four years, answered that it was to have an egg a day.
