I know that Jens came over from Denmark at some point between his birth and marriage to Caroline Pavey in London. Marriage was 1887 and certificate states Jens had changed his name to James, and was aged 36 at time of marriage to Caroline, so born about 1851. He had two sons with her, Frederick (b.1888) and Herbert (b.1890). Frederick changed his surname to Morton, whereas Herbert kept his as Mortensen. Ideally i would like any info on the Danish connection, but any would be greatfully received. Thanks in advance for your time
