Many. many thanks so far for all this information. The death in Belfast in 1962 is the correct man but the date much earlier than I was led to believe (from the person who got the medals via the person Victor gave them to).
With the death date I found the following-
1951- Belfast directory- The Straight: 21. Victor Hoyland, engineer (also 1955, 1960)
The person he gave the medals to was a neighbour and she and her husband are also listed in the same street.
Northern Whig, 3 Apr.1962: HOYLAND — March 31, 1962, Captain Victor Hoyland, 118, The Straight. Funeral from Wilton's Funeral Home. Woodstock Road, to-day (Tuesday), at 11 a.m., to Roselawn ...
Hoyland, Victor of 11B The Straight Cregagh Belfast departmental manager died 31 March 1962 at Musgrave Park Hospital Belfast Administration Belfast 25 June to Colonel Stanley Joseph Hoyland. Effects £978 13s. 5d.
Not sure if he came to Belfast for employment after the War or to do with his wife (supposed to have had no family and been unmarried but like Chinese Whispers the 'facts' aren't always correct).
Hoyland Agnes Young of 21 The Straight Cregagh Belfast died 19 September 1958 at the City Hospital Belfast Administration Belfast 27 November to Victor Hoyland assistant production controller the husband. Effects £23 0s. 6d
According to death reg. he was born c1904 but c1905 from cemetery records. Only close birth in England (none in Ireland) is a Victor Hoyland J/M 1904 Portsmouth dist. (mother's maiden name Wheeler) mentioned earlier.
Will keep checking more more details and probably view his death certificate in case there are any clues there.
