Joseph Lombardo
Lombardo has always kept silent about his family over the years, but his family is rather significant and important; Lombardo married Marion Nigro in a Catholic ceremony in 1951. Lombardo appears to have two brothers named Ralph and Rocco. Lombardo lived in the same modest condominium building on West Ohio Street, on the Near West Side of Chicago, from the time he was married until he became a fugitive in 2005.
Bobby Capó
Capó married Irma Nydia Vázquez, the first Miss Puerto Rico to participate in the Miss America pageant and the daughter of a wealthy Puerto Rican industrialist, in 1948. The marriage was frowned upon by her family, and he wrote: "El Bardo" ("The Bard") inspired by this. "El Bardo" tells of a pauper who died heartbroken after his wealthy love prospect marries another man, and finishes up with her (also heartbroken) reaction to his death. The song was a huge hit for Felipe Rodríguez in the early 1950s and has been covered by many others. 
Capo had six children: Félix Manuel Rodríguez (musician Bobby Capo Jr, father of Pedro Capo), Irma "Mimi" Rodríguez López, Soraya Rodríguez, Waldo Rodríguez, Jacqueline Rodríguez (also a singer) and Zahera Rodríguez.
