The title "The Milkmaid's Lot" refers to a quote attributed to Queen Elizabeth I while she was imprisoned in the Tower of London. Supposedly, the queen looked down from the Tower one morning, saw a young milkmaid singing to herself as she cheerfully went about her chores, and remarked, "That milkmaid's lot (in life) is better than mine." As such, the title also refers to Margaret, the "queen" of Nucky's empire: while she has a position of power and privilege, she feels trapped and longs for a simpler life.
The episode won 2 Emmy Awards for Outstanding Sound Mixing for a Comedy or Drama Series (One Hour) and Outstanding Sound Editing for a Series.
