The Child Thou Gavest Me (1921)

On her wedding day, Norma Huntley wants to tell Edward Berkley, her husband-to-be, her secret -- that she mothered a child out of wedlock which subsequently died. Her mother forbids her to reveal this. Only moments after the ceremony, it is discovered that the child, now three, is actually alive. Berkley, incensed at this turn of events, agrees to adopt the child and remain married for appearance's sake -- but when he finds the father, he will kill him.
