Highland Roots - Family History from the Heart of the Scottish Highlands
|Clans - Histories & Genealogies
The Family History Room in the Highland Archive and Registration Centre probably has the largest collection of clan and family histories relating to the Highlands - all of which should also be found in the National Library of Scotland, whose catalogue may show many more: www.nls.uk/catalogues.
A guide to published histories & genealogies of Highland clans is currently being compiled by Highland Roots in association with the Highland Family History Society, who hopefully will publish it when it is complete.
In the meantime, the two standard reference works - now both badly out of date - are:
Margaret Stuart & Sir James Balfour Paul, Scottish Family History
