  • We were so sad to hear of Jack’s passing. When he lived in Easton he would pop in, often without notice…we truly enjoyed those visits. He always called me “wifey”.

    Jack was a caring, sensitive man, who loved his family. He was so proud of his children and grandchildren.

    As a friend to my husband, he was a unique individual…you could count on him if you needed him.

    We were saddened when he made the move to Delaware, but he wanted to be nearer to his mom…what a great son.

    Again, our sympathies to Cody, who we knew, and to Mrs Slack and the rest of the family, who we knew of.
