The website for the Outer Hebrides, called Hebrides People has now added families for the Point of Lewis (the peninsula extending east from Stornoway).
The website is a pay-per-view through the purchase of credits. From their notice comes the following information:
"The database also allows access to two further unique features - family notes and family sheets. These take the researcher beyond research into individual persons to research into whole families. The family notes give a summary of the family history. They are based on the 1851 census as a datum-line, working back as far as possible – usually to the generation born in about 1750/60, and forward as far as 1920. The family sheets are hand-written work-sheets, compiled by Bill Lawson for each family, showing the lines of descent in the male line, together with cross referencing of the female line to their spouses’ family sheets. There is also a gazetteer available, with a summarised history of each township for those less familiar with Harris."
