Dan Shea (who earned his Ph.D at SU under Edrei in 1965) had gone to a party in 1963 given by a TA in English, had met Helga there and told John about her. Helga had earned a BA in 1955 at Hartwick and was teaching English at East High in Rochester. Dan arranged that the three of them go on a picnic on Labor Day in 1963. In 1964 John and Helga were married and they have two children John III and Laura. John III is married to Deborah. Laura is married to Michael, and they have a daughter Connie and a son Jackson. Helga taught for 20 years in the writing program at SU, and died in December 1998 after a long illness.
John III and his wife often have John over for dinner, and Laura and her husband have him visit them in Philadelphia several times a year. John III has driven him half way to Philadelphia, and Michael has driven up to meet them. John particularly enjoys his young grandchildren.
