It's not the words out of President Kennedy's mouth or was it from any family member, and we really know to where Kennedy was born.
Furthermore, the the website you give us already qualified the word 'home' previously...that it was his "ancestral home" as it says below:
The Kennedy library website: "...first captains of the Constitutional Navy, was born in County Wexford, Ireland, the ancestral home of President Kennedy. President Kennedy displayed the pennant in the White House Oval Office."
