A U.S. woman born six weeks after the abortion of her twin brother is jetting in to Ireland to address pro-life rallies.

The mother of Claire Culwell, now 30, had one amniotic sac removed when she was six months pregnant, but her daughter was in a second, undetected sac.

Claire grew up in an adoptive family with just one sister — but traced her birth mother at the age of 21.

Claire, travelling to Dublin this week to speak at a series of rallies organised by the Love Both Project and the Pro Life campaign, explained her personal story from her home in Texas.

She said: “I’m not nervous. I’ve heard a little bit about the debate going on there, but I’m just coming to share my story, I’m not coming to debate people.

“I do know that my story will offend some people in Ireland, some people might not want to hear it or may choose not to hear it, but I think personal stories are what change people’s minds.”

Claire grew up knowing she was adopted, but never knew why she had so many health complications.

She said: “I was born very prematurely, my hips were dislocated on both sides and I had club feet.

“I went through multiple body casts until I was two years old.”

When she met her birth mother Tonya nine years ago, she discovered her mother, who was 13 when she became pregnant, had undergone an abortion at five months.

Claire explained: “There was no conversation. When my birth mother approached her mother and said ‘I’m pregnant’, her mom said, ‘You’re 13, you’re in eighth grade, you’re not ready to be a mother, I’m not ready to be a grandmother’.

“There was no discussion. She just said that her mother’s answer was to get rid of the baby.”

Tonya underwent an abortion, but four weeks later it emerged she was still pregnant.

A doctor then confirmed that the procedure had removed one amniotic sac, but Claire was in a second, undetected sac.

“She was heartbroken. She said her life never went back to normal, and she continued to have children at a young age."

Because the 13-year-old had reached six months’ gestation, the doctor refused to perform a second abortion — so Tonya’s mother brought her to Kansas which had less restrictive laws.

But Claire said: “The doctor in Kansas said he couldn’t do it either. We were fraternal twins so my twin was in one amniotic sac and I was in the other.

“When they removed his sac they ripped mine, so my birth mother had been leaking amniotic fluid for four weeks.

“Doing a second abortion would have been very dangerous for her, so she was put on bed rest.”

Two weeks later, two and a half months premature, Claire was born.

She said: “Tonya spent about two days with me. She was able to feed me and hold me and spend time with me.

“After two days she left me. I stayed at the hospital until my adoptive parents picked me up at two and a half months old. I was just five pounds.

“It was very, very hard for her. She said she wishes there had been a place back then, maybe a home that could have helped her learn how to be a mom so she could have kept her baby. She didn’t necessarily have a choice. This was her mother’s choice.

“She was heartbroken. She said her life never went back to normal, and she continued to have children at a young age.

“She had another daughter two years after me, and another daughter two years after. I think she was trying to fill that hole in her heart.”

Claire added: “It was one of the saddest things that I have ever heard in my life, especially thinking about a 13-year-old going through this.”

While she never used the term ‘pro-life’ growing up, Claire says she always felt in favour of alternatives to abortion because of her experience of adoption.

However, she said the discovery of her mother’s experience inspired her to speak out, saying: “We could keep abortion legally out of Ireland, but if hearts are not changed there are still going to be women having abortions.

“I truly believe that women, men, families and children deserve better.” Her stance has become even more personal since she became a mother herself.

And she recalled one occasion that saw her travelling to Canada to speak at a rally when she was six months pregnant.

She said: “At that stage, there was no denying I was pregnant and yet they told me that in Canada the law would have allowed me to have an abortion for any reason up to nine months.

“I look at my daughter often and think, if that abortion had taken my life, my little girl wouldn’t be here.”
