MADRID — She devoted years to caring for her mother, who died at age 101. Then, Maria del Carmen Bousada embarked on a quest to become a mom herself. She lied to a California fertility clinic to skirt its age limit, and later pointed to her mother’s longevity as a reason to expect she’d be around to care for her kids.

At age 66, she had twins, becoming the world’s oldest new mom — and raising questions about maternity so late in life. Now, she is dead at age 69, leaving behind boys not yet 3.

Bousada’s brother told the Diario de Cadiz newspaper his sister died Saturday. He had said in November that she was being treated for stomach cancer.

Shortly after her sons, Pau and Christian, were born in December 2006, Bousada reflected on her decision to deceive doctors.

“I think everyone should become a mother at the right time for them,” she told the British tabloid News of the World, which showed her beaming as she cradled her 1-month-old infants. “… Maybe things shouldn’t have been done in the way they were done, but that was the only way to achieve the thing I had always dreamed of, and I did it.”

Beginning in 2005, Bousada underwent hormone treatments to reverse years of menopause and sold her house to pay for in vitro fertilization at the Pacific Fertility Clinic in Los Angeles.

She told the clinic she was 55 — the facility’s maximum age for single women undergoing the procedure. When her sons were born, Guinness World Records said she was the oldest woman on record to give birth.

Dr. Vicken Sahakian, director and owner of the clinic, said Bousada falsified her birth date on documents from Spain. “I figured something might happen and wind up being a disaster for these kids, and unfortunately, I was right,” he told The Associated Press.
