San Francisco 49ers Star Trent Williams, Wife Sondra Williams Share Baby Boy Has Died at 35 Weeks

Trent Williams and Sondra Williams are grieving a devastating loss.

The San Francisco 49ers offensive tackle and the yoga instructor shared that their son Trenton O’Brien Williams Jr. was stillborn at 35 weeks after losing his twin earlier in her pregnancy.

“It’s been extremely hard trying to process the saddest Hello and Goodbye that I’ve ever had to endure,” Sondra wrote on Instagram Dec. 1. “I welcomed your lifeless 4lb 8oz 18.5 in long little body at 11:38 p.m.”

She shared that Trenton had been diagnosed with trisomy 13, a rare genetic condition that occurs when a person has an extra copy of chromosome 13, according to the U.S. National Library of Medicine. Most infants die within their first few weeks of life and only five to 10 percent live past their first year.

“As much as I tried to prepare myself for our meeting, I wasn’t prepared, nor would I ever be,” she continued. “After losing your twin early in the pregnancy, I prayed and hoped that your diagnosis of Trisomy 13 wasn’t true and wouldn’t be the fate of my long awaited beautiful Son-shine.”
