Maureen Posler wrote a sympathy message

“I remember John fondly! Growing up on Tuller in Detroit, the Treanor house was the “fun” house and with all the kids, something was always happening. Like many of the Irish neighbors, John and Kathleen looked out for each of the neighbors. I lost track of him until I joined the LAOH a few years ago. Rest in peace you! Your family will miss you! Maureen Dillon Posler.”
