I can find no record of military service for John during World War I.
On 7 June 1929 John McKillop married Eleanor Potter whose birth name was Eva Hood McPhail. They married at 63 St. Vincent Crescent in Glasgow according to the forms of the United Free Church. John worked as a subway car driver and Eleanor as a subway station mistress. They had one known child, Eva McPhail McKillop, who was born in 1932 in Glasgow.
John McKillop died on 23 October 1960 of pulmonary tuberculosis from which he had suffered for 6 years. Two days before his death he also suffered from congestive cardiac failure. He died at Rodroyston Hospital, but resided at 308 Netherton Road and was a retired tram car driver. His son-in-law, a Mr. David, registered his death with government authorities.
