For decades, unwed mothers in Italy were pressured to give up children born out of wedlock. Thousands were sent to America. Now some families are reuniting and looking for answers.

During the 1950s, the Catholic Church in Belgium separated thousands of newborns from their unwed mothers and put them up for adoption, often without the mothers’ consent. The women were shamed into surrendering their babies by their families and a powerful church. Last month, Pope Francis apologized for those forced adoptions.

But Belgians weren’t the only victims. From 1950 to 1970, the Vatican sent 3,500 Italian children to America on something called an orphan visa. The trouble was most were not orphans. Like their Belgian counterparts, they too were the children of unwed mothers. Many mothers later went searching for their children, only to discover they had been sent across an ocean. Today, thousands of American adoptees are still struggling to piece together their lost lives.
