The Irish-American Catholic Church Sullivan brothers are introduced through a progression of baptisms: George Thomas in 1914, Francis "Frank" Henry in 1916, Joseph "Joe" Eugene in 1918, Madison "Matt" Abel in 1919, and Albert "Al" Leo in 1922 in their hometown of Waterloo, Iowa. There is also a sister, Genevieve, nicknamed "Gen", making the Sullivans a happy family of eight.
