John and Gloria raised three children: David William Coyne, Steven Lee Coyne and Kimberly Jean Coyne. He loved spending time with his family, especially camping, boating, attending town festivals, and supporting his children and grandchildren at school and community events.
He was active in the community through organizations including the Indian Guides, Boy Scouts, Kiwanis Club, and the YMCA.
John was predeceased by his brothers, Donald and Bill Coyne, and wife, Gloria.
John is survived by his children, David William Coyne, Steven Lee Coyne and Kimberly Jean Robinson; his grandchildren, Christopher Wilcox, Jason Coyne, Tyler Coyne, Markie Mercado and Hannah Robinson; and his younger brother, Rick Lee Coyne of Montana.
