I have a Kennedy family buried at Versaille Cemetery in Pittsburgh who seem to be connected to Kennedy Township in Pittsburgh.Some of the family were bankers connected to Banking family of Mellon family.
I know for sure by Versailles Cemetery Records that President John F Kennedy visited the grave site just before he was elected. He was with Mayor Lawrence.The Lawrence family is about 100 ft from the Kennedy's.
All of them seem to be connected to the Nixon Theater in Pittsburgh owned by actor and dancer Gene Kelly.
Then all of them have a connection to the Corn Exchange Bank in Philadelphia.
