There is a Robert Snape in the Eng 1891 census:

RG12/3221, 15, 114, 38, Salford Lancashire (can't read street name)
Thomas Snape, Head, 26, b.Manchester, Lancashire
Maria Snape, Wife, 25, b.Manchester, Lancashire
Robert Snape, Son, 5, Scholar, b.Manton (Newton?) Heath, Lancashire

I also found a Ruth Callin in the IOM 1891 census:
RG12/4682, A, 4, 101, 12, German, Balla??
Danl, Head, Mar, 45, Lead miner, b.Patrick
Evelyn, Wife, Mar, 39, b.Patrick
Lizzie, Daur, Single, 10, Scholar, b.Patrick
Florence, Daur, 9, Scholar, b.Patrick
Thomas, Son, 7, Scholar, b.Patrick
Ruth, Daur, 5, b.Patrick
Eva, Daur, 3, b.German
Mira, Daur, 1, b.German
Richard, Grandson, 1, b.German

These are the only close matches I can find in 1891. Hope this helps.
