Hi Louise, well I know very little about my Sanders/Saunders family, they don't appear to be on any of the census returns. Elizabeth Sanders/Saunders (from one of her childrens birth certs, very difficult to read) was born c1831 in ?Petrockstow, Devon. She was my ggg Grandmother, she married William Bissett in c1858 in presumably Torrington. I don't know who her parents were, but she had a sister called Mary c1833 ?Petrockstow. I see that your Saunders were a travelling family, could be possible, if they are linked, that this is why I can't find mine on any of the census' until she is married to William.
My Scoins are also connected to the Bissett's, Elizabeth and Williams Bissett's son George married an Annie Scoins c1867 Bideford, Devon. Her parents were George c1833 Parkham, Devon and an Honor Wade c1835 Bradworthy, Devon. Her siblings were Mary Jane c1856, Elizabeth c1858, Matilda c1862 all born Parkham and John c1869 Bideford. George's parents were John c1797 Parkham and Ann Wakely c1796 Stealton, Cornwall. His siblings were Reuben c1836 and Elizabeth c1838 both born Parkham.
Reuben married an Ellen ? c1849 Hartland, Devon, they had 6 children, William c1870, John c1872, Fredrick c1875 all born Northam, Devon, Emma Jane c1876 born Littleham, Devon, Matilda c1878 born Bideford and Florence c1880 born Littleham.
Hope this helps
Regards
Kate.
