I have checked the transcriptions and they seem fine.
The ages show some 'creative licence' however:
1851 - Eliza Squire, unmarried, 23
1861- Eliza Seymour, unmarried, 33
1871- Eliza Squire, unmarried, 42
1881- Eliza Seymour, unmarried, 48
1891- M. Eugenie Seymour, widow, 63
1901- Eliza Squire, unmarried, 73
1911 - Eliza Squire, unmarried, 84
If M Eugenie Seymour (1891 census) is a different person, then I am unable to find Eliza Squire in 1891, and Eugenie comes from the same birthplace as Eliza Squire, and is also aunt to Eliza Frederika Butler.
I remain perplexed!
