Hi
Just found the 1911 census entry for Ethel Pearson looks good but it gives her as sister but the age gape looks wrong.
I might have found her in the 1901 census she is 13 living with widow mother Emily, 52 and brothers Walter, 15 and George 7. (George missed of the index so does not show up.) they are living at 10, Parkfield Street, Islington is this in the right area for St. Johns.
Cannot find them in any of the other census's.
John
