WOW Jason - cool map. Haven't seen one like that before - looks like a world invasion by the Blaikie, Shields and Nutes.
Some more names and detail to add......
I think I have found Elizabeth in 1851, indexed under the name of METE. This post is getting a little long

to be jumping back and forth for reference, so I have included again the 1861 entry for the family below:
1861Elizabeth Nute 44, head, unmarried, housekeeper, b. St Stephens Cornwall
Willice Nute 10, b. St Stephens Cornwall
Bessey Nute 8, b. St Stephens Cornwall
Ellen Nute 6, b. St Stephens, Cornwall
Jabez Nute 3, b. St Ives Cornwall
Charles Nute 2, b. St Ives Cornwall
Mary Jane Roberts 2, relative's child, Devonport, Devon
Address: St Ives, Cornwall
I think this is them in 1851 in St Stephens By Saltash Cornwall ~ still no sign of John Nute, the reputed husband:
1851Elizabeth NUTE31 schoolmistress (didn't expect this) b. St Stephens - still unmarried

John S,NUTE 5, b. St Stephens
Willis NUTE, 7 months, b. Devonport Devon
Stephen NUTE, 25, brother, agr. lab, unmarried, b. St Stephens
Possible birth entry for some of the children, can't see anything as yet for Ellen and Bessie:
Births Dec 1846
Nute John Stephen St Germains 9 114
Births Sep 1857
Nute Jabez Liskeard 5c 62
Births Jun 1859
Nute Charles Liskeard 5c 62
Thinking of a possible death for a John Nute Snr, these are the only ones coming up between 1855-70:
Deaths Dec 1860
Nute John St. Germans (Cornwall) 5c 21
Deaths Dec 1865
Nute John Tavistock (spans Cornwall and Devon) 5b 252
Deaths Mar 1870
Nute John 70 Totnes (in Devon) 5b 154 ~ probably too old but who knows
