Mervel (transcribed on Ancestry as Meriel) had banns read as a Clavering Craig in Charlton and according to this record married a Clair May Brown of the parish of St James', Farmley, Yorks on 7 Nov 1918. I can;t find this on FreeBMD to check what name he used at the actual marriage (or much evidence of her with that spelling of Clair either)
