Ages Of The Characters (Per Barry's Play)

For those yet curious about the age difference between Dinah and Tracy, I just dug up a copy of the play. The characters are described thus:

Dinah is “all of fifteen years old.”

Tracy is “a strikingly lovely girl of twenty-four.”

Margaret Lord is “a young and smart forty-seven.”

Alexander “Sandy” Lord is twenty-six.

Uncle Willy Tracy is sixty-two.

Mike Connor is thirty.

Liz Imbrie is twenty-eight.

Mac The Night Watchman is thirty.

George Kittredge is thirty-two.

Dexter is twenty-eight. "Pleasant and good-looking."

Seth is "tall, handsome, suave. Fifty."
