And in 1891, the same 3 sisters are in Bootle, West Derby, Lancashire

62 Park Street
MA ARCHER 71 (b abt 1820), widow
Jane MURRAY 72, (b abt 1819) unm,
Eleanor MURRAY 47, (b abt 1844) unm,
All: Living On Own Means, and listed as : b Walton, Hertfordshire
In the 1881 that you have, they were stated respectively as ages: 56 (b abt 1825) , 59 (b abt 1822), 37 (b abt 1843). So a wee bit of a discrepancy there for Mary A and Jane…..but clearly the same women.
Pretty sure their place of Birth is meant to be Watton (Watton-at-Stone). Misheard - or misread - twice by the Census enumerator? Pretty sure this following is Mary Ann and Jane in 1851, both as yet unmarried and with their own widowed mother Mary and two brothers, in the household of mother's father Thomas PEET. They're in St Andrew Herts, which is in the Watton civil area - and the girls have again been transcribed as being born Walton. But the image says Watton, I'm sure of it.

You say you're after finding your gt-gt grandmother Jane. The Jane MURRAY in these census is unmarried - does that fit with what you know of your Jane?
