Baby Boy Born from 1994 Embryo Becomes Uncle at Birth

LONDON — A baby boy born in 2025 from an embryo frozen in 1994 has set a new record in reproductive science and created a rare twist in family lineage.

Thaddeus Daniel Pierce, born July 26, is biologically younger than his sister, yet entered the world as her daughter’s uncle.

Thaddeus’s embryo was created in May 1994 during fertility treatment between Lydia Archerd and her then-husband.

One embryo led to the birth of their daughter that same year. The remaining two were cryopreserved and left untouched for more than three decades, while Lydia continued paying annual storage fees.

“I always called them my three little hopes. Even after I reached menopause, I couldn’t let go. They still meant something,” Lydia told MIT Technology Review.

In 2024, Lydia chose to donate the remaining embryos through Nightlight Christian Adoptions, a nonprofit specializing in embryo adoption.

The match was made with Lindsey and Tim Pierce, a couple from London, Ohio, seeking to grow their family.

After legal and medical clearance, one embryo was transferred at Northeastern Reproductive Medicine in Tennessee.

Nine months later, Thaddeus was born healthy and full-term.

At 31 years old, Thaddeus’s embryo is the oldest known to result in a successful birth, surpassing previous records held by twins conceived in 1992 and Molly Gibson, born from a 27-year-old embryo.

“We weren’t trying to break records. We just wanted to become parents,” said Lindsey Pierce.

Thaddeus’s biological sister, born in 1994, now has a daughter of her own — making Thaddeus both her younger brother and her daughter’s uncle from birth.

“When I first saw him, I couldn’t believe it. His face looked just like my daughter’s did when she was born. It felt like holding time itself,” Lydia said.

Experts estimate tens of thousands of embryos remain in long-term storage, often due to divorce, age limits, or changes in family plans.

Lydia’s decision to donate was driven not by science, but by memory and conviction.

“I knew they were mine. But they weren’t mine to raise. I held onto them because I believed they still had a chance and now one of them is living that chance,” she said.

Thaddeus’s birth is more than a medical milestone. It’s a story of life delayed, not denied — a reminder that possibility can wait, and love can preserve it.
