She is pictured with her mother, 93-year-old Marcella, who is now a great-great grandmother.
The Herald published the photo of mum Marcella and her young tot Sarah in January 1963.
Fifty years later the pair came together for another loving photo as Sarah's milestone birthday approaches tomorrow.
Sarah was born in her home on Carna Road, Ballyfermot, in Dublin at 00.14 on January 1, 1963.
Super mum Marcella -- who gave birth to 12 children -- is still living in the same house.
Sarah was Marcella's 12th and final child and the pair are still as good pals as ever.
"We are still very close and she is still living in the same house and doing great," Sarah told the Herald.
"She will outlive us all," laughed Sarah -- now a mother herself -- who will turn 50 tomorrow. Marcella has welcomed a generation of Doyles into the family since her last child was born 50 years ago.
Not only is she a granny to 28 grandchildren, but Marcella also has 37 great grandchildren and four great-great grandchildren.
And Sarah says that her mum is doing well and is enjoying her life after rearing Sarah and her 11 siblings.
"She's great and in good health -- she's never been sick thank God," Sarah told the Herald.
Sarah, who works as a care assistant in a Dublin hospital, has three children and four grandchildren of her own.
She is looking forward to her New Year's birthday, but says she will not celebrate the occasion on the day.
"We won't celebrate properly until a bit later in January because most people usually have plans at New Year.
"I will have a party in the house for the neighbours and friends on January 12," she explained.
Sarah, who lives just around the corner from her mother in Ballyfermot, says that the photo is a great keepsake for her.
She mislaid it but was delighted when her own daughter Sarah Jane found it.
"I used to have it when I was younger before I mislaid it and would show it to all my friends so it's great to have it back," she said.
