The house is at the end of the road, nestled behind a playground in Loughrea, an ancient town in County Galway. Built of white stone with gray trim, it has lace curtains, a statue of the Virgin Mary and two small bedrooms, one pink, the other blue.

In the living room, a small, fragile woman in a plaid skirt sits in an overstuffed orange chair. She is 93 but lives alone, with an overweight mutt named Rex. Day after day, she busies herself with small tasks — praying the rosary, hanging the wash, letting the dog into the yard — while she waits for the return of the son she never got to hold.

She has been waiting for 76 years.

A Home of Shame and Secrets

As a teenager, Chrissie Tully fell in love with a man in her neighborhood, and in 1949, she became pregnant.

What happened next would follow a grim, common script in midcentury Ireland, where the Catholic Church and its rigid doctrine dominated nearly every aspect of daily life. Ms. Tully’s family disowned her; the town, Loughrea, spurned her. A priest took her to St. Mary’s Mother and Baby Home, a facility for unwed mothers in Tuam, 30 miles north.

Such institutions remain one of Ireland’s enduring moral stains. Independent panels have excoriated them, religious institutions have apologized for them, and the Irish government has bumbled through a redress scheme, seeking to financially compensate tens of thousands of Irish mothers and children who were banished to them.
