Pembleton was born into a Catholic family in New York City on July 1, 1961. It was implied that he had siblings, but they never appear on the show. He was educated first in a Catholic elementary school and then in a Jesuit high school, a reference to Braugher attending a Jesuit school, St. Ignatius College Prep, in Chicago. Frank later said that "the Jesuits taught me how to think," which comes up on the show from time to time. He knows Latin and Greek and is well versed in Catholic theology. He met his future wife, Mary, on the Great Lawn in Central Park shortly after graduating from the police academy when he was 24. He claims that he knew as soon as he met her that she was "the one." They were married in 1986.Homicide: Life on the Street episode "M.E., Myself and I", originally aired November 1, 1996.
