1861 census RG9 3619 folio 116
Quay Scarborough Yorkshire
Felix Marlow 26 Liverpool, Lancashire, Head Married Mariner
Sarah Marlow 24 Scarbro, Yorkshire, Wife
Sarah J Marlow 2 Scarbro, Yorkshire, Daughter
The next three censuses place Felix's birth year nearer 1833.
FreeBMD has Felix's two marriages
Marriages Dec 1857
Marlow Felix Scarbro' 9d 596
Stonehouse Sarah Scarbro 9d 596
Marriages Jun 1897
Marlow Felix Scarbro' 9d 632
Porter Mary Ann Scarbro' 9d 632
I would suggest ordering one of these certificates to confirm Felix's father's name and occupation and to aid searches on earlier censuses.
