If you haven't already, check out the hjackwells3 database on rootsweb.When you get to Rev. James Alexander b. 1634, in family view mode click on "Other Parents" which will take you to alternate father Robert Alexander (Wells has Sir William Alexander as primary father of Rev. James, but Robert as Rev. James' father comports with Joanne's research, which is right on).This route will take you back through the Lords of the Isles and Robert the Bruce to Somerled.Some information is inaccurate, but Wells includes copious notes and cites his sources, ranking them as to quality.I have found much that is interesting and useful in his upload.
