You should be able to find the family in the 1911 census which will help you find some siblings for her.
As Don suggests, have a look at some of the search results on SP for clues. For example, there is this death in the Black Isle: Donald MacLean, 77, mother's MN Fraser died in 1982. A possible brother? Given the approx birth year, if a sibling, should show in 1911 with family likely.
