Isabella, born 1842, was the daughter of Alexander Munro and Marion Martin of Ruisgarry. During the 1840s, with re-organisation of Ruisgarry’s small crofts into larger ones, the family moved instead to Borve. The ruins of their house, Tobhta Alasdair 'ic Anndaidh, are still evident.

However, in 1854 the crofts were taken for Borve Farm, and the family moved to Arnish, Lewis, later living at 20 Branahuie. Isabella remained unmarried, passing away in 1917.
