Lillie Cooper celebrated her 100th birthday surrounded by members of her family.
The gathering took place at the East Cosham House residential care home, where she has lived for the past 10 years.
Lillie’s son, Roy Cooper, says: ‘It all went off quite well.
‘Everybody was chatting and laughing.
‘The staff are magnificent, and they had a lovely bunch of flowers for her.’
Lillie was born on November 15, 1914.
Her father, Thomas Jones, served in the Middlesex Regiment in France in the First World War.
He chose his children’s names based on his travels, and named Lillie after the city of Lille and his second daughter, Nancy after the city of Nancy.
Lillie was born in Gruneisen Road, Stamshaw, and has lived in the same area all her life.
She married Frederick Cooper in 1936.
Their only son, Roy, was born in December 1939 – like his mother, just a few months after the start of a major conflict, this time the Second World War.
Lillie was a housewife all her married life, and celebrated her diamond anniversary in 1996.
Frederick died in 2002, aged 92.
Before retiring he worked as a shipwright in Portsmouth Dockyard.
Roy says Lillie has been very happy at East Cosham House and has received excellent care.
She is the oldest resident at the care home and has refrained from smoking and drinking throughout her long life.
