I wonder ...

In 1911 in Nottinghamshire a few Ellens 14 yrs old, some 20 or older, but just one in between:
Ellen Holmes abt 17 yrs old, boarder in Mansfield. Born abt 1894 Ilkeston. She would need permission in 1912.

In 1901 this one seems to match:

Name: Ellen Holmes
Age: 7
Estimated Birth Year: abt 1894
Relation: Daughter
Father's Name: Thomas Hendley
Gender: Female
Where born: Sandiacre - close enough to Ilkeston?
Household schedule number: 177
Piece: 3220
Folio: 143
Page Number: 27
Household Members:
Name Age
Thomas Hendley 30
Mary Ann Hendley 29
Ellen Holmes 7
Rachel Hendley 7
And a bunch of relatives of Thomas Hendley:
Effel Hendley 10
Liza Hendley 13
Thomas Hendley 48
James Hendley 23
Emily Cockayne 24

If I were Ellen, I'd run away from that too!
