John Peter McKenna, commonly known as Jack, Dad, and Grandpa, passed peacefully at home surrounded by his loving family on April 29, 2021. He was 80 years old.
Jack was a first-generation Irish American, the son of the late Peter McKenna & Katherine (McGinty) McKenna of County Monaghan and County Donegal respectively. He was born on June 10, 1940 in New York City and was raised in Queens, N.Y. He attended Power Memorial Academy H.S. and served in the U.S. Coast Guard at the ripe old age of seventeen. A graduate of St. John’s University, Jack went on to become a career IBMer holding positions in sales and management, which enabled him to travel all corners of the globe. He lived by the motto play hard but work harder.
Together with his former wife Joan they raised three girls in Dix Hills, N.Y. and resided there for over twenty-five years. Jack wisely retired at the age of fifty-five and moved to sunny Florida. He spent his later years golfing, traveling, and dabbling in real estate. Jack was a proud member of AA for eighteen years where he formed strong friendships and devoted his time to hosting local AA meetings along with sponsoring members in need.
