Stansbury said she had not sought out any possible family connection in Williams' native Wales because of his common name.

"After 10 years in the lab, maybe it's time for these guys to get out of archival boxes and into a final resting place," he said. Fund-raising has also begun to erect a monument in Arlington to the 16 men on the Monitor, which he called an "iconic warship that changed naval history."
"Like all who served and all who do pay the price, that in and by itself makes them important and worthy of remembrance and recognition," Delgado said.
