I'm looking for a death record for Margaret Grant, born 30 October 1872 in Mears Ashby, Northamptonshire to Alexander Grant and Elizabeth Croal (they were Highlanders and only spent a short part of their lives in England).
Margaret was from a family of 10 who lived in Arisaig between 1880 and 1905; I have identified them on the 1881, 1891 and 1901 censuses - and beyond.
I am having trouble with Margaret, however: she only appears on the 1881 census, and I cannot find a record of her death between 1881 and 1891.
I can find a death record for her sibling Charles in 1883, and I have found their family tombstone in Arisaig from the 1940s: this has a couple of family members and their wives, but doesn't mention Margaret. The remaining family members are buried in St Mary's Church, Langley, Berkshire.
Where should I look next for clues?
