otherthe step brother but the father of the step brother. If my assumptions are correct then George Jr. is not even the step brother of Jimmy Burke. The mother of George is not the same mother as Jimmy Burke. If George Sr is not the father of Jimmy then it follows George and Jimmy are not biologically related. I have been told by several sources that both Jimmy and George Jr have said Jimmy The Gent have often said Jimmy /the Gent is their uncle. Jimmy's mother is FRANCIS Burke, maiden name LoC....... No need to put anyone else's name into this.
