I have a half 2xgreat uncle who was born in London in 1873 by the name of Frederick Magnus Hartvig. His father was reputed to have been a tea merchant from Sweden. His mother was Emily Janes. On the 1901 census he is shown as a policeman, recently married to a Harriett Richards (known in the family as aunt Hatty).
On the 1871 census for London in the Camden Town area there is a Hugo M Hartvig, aged 20, originating from Sweden. He is shown as a boarder, and student. Does anyone recognise any of these persons and can offer any further information please?
