I've now got Rebecca Haysom's marriage certificate. According to this, my gg grandfather, James George Milton married Rebecca Haysom on 25 December 1859 in the parish church in Stepney, Middlesex, London, England. He was 25, she was 22. They were both cordwainers by profession. His father was James Milton, also a cordwainer. Her father was William Henry Haysom, a packer.
