My Cousin Did Trace this re the Hargraves name - this would put her birth at 1868 instead of 1875??
That would make her age when she died as 96.

1871 Census
41 Carlton Rd, Worksop, Nottinghamshire
HARGRAVES
Cowshaw, head, married, 44, Wesleyan Minister, born Ganshawn, Lancashire
Sarah Ann, wife, married, 40, born Cumberland, London
Elizabeth A, daughter, 14, scholar, born Burton on Trent, Staffordshire
John T, son, 13, scholar, born Fordingbridge, Hampshire

Lilian, daughter, 8, scholar, born Scotland
Theosophilis C, son, 7, scholar, born Scotland

Just throwing that into the pot for comment.
