There is in FindMyPast an item headed "Preston Decrees" in the Lancashire Evening Post issue of 21st October 1954 which reports that:
"At Preston Divorce Court, today Mr Commissioner Maddocks granted a decree nisi, in [an] undefended case, to Brian Robert Martin, Lowthorpe Road Preston, desertion by Mary Martin"
Also in FindMyPast is a detailed report, from the Nelson Leader of 10th October 1941 of their marriage on 4th October at St Mary's Church in Nelson.
