We haven't found any trace of William and Williamina yet although we have found varous members of the family in the Kinlochbervie and Scourie areas after 1844.It is possible that they moved to Achlyness (Achiness) which is where John and Barbara(Mackenzie)were living in 1851. Certainly family history has it that they were cleared from Kinsalie to Achlyness. Alternatively they may have moved to the Scourie area where there were Falconers living in 1891.
Do you have any information on John and Barbara Mackenzie's family? Would be interested to hear.
