Francis Wayne Sinatra was born January 10, 1944, in Jersey City, New Jersey, into the household of one of the most popular singers in the world, Frank Sinatra. The younger Sinatra, who was not technically a "junior", but was known as Frank Jr. throughout his life, hardly saw his father, who was constantly on the road, either performing or working in films. However, Sinatra recalls wanting to become a piano player and songwriter from his earliest days.
