"In any event, Cromwell forced the Catholic natives of Ulster off their highly desireable farmlands, banished them to the relatively barren rocky west, and forcibly repopulated the area ("plantation") with Scottish peasants/farmers from just across the water, thereby "planting" a more cooperative population, forefathers of the future Orangemen and Loyalists."

I don't think you've got it right there. The Scottish Plantation of Ulster started in the early 1600s and was instigated by James VI of Scotland when he ascended to the English and Irish thrones after the death of Elizabeth I. He hadalready carried out similar smaller scale exercises in moving Lowlanders into parts of the Highlands. There was a significant established Ulster-Scots population long prior to Cromwell. It was reduced somewhat during the civil wars dsepite there being a Scottish amy in Ulster to protect the colonists whilst the main Scottish army was occupying northern England. Scotland and England though were completely seperate countries which just happened to share a monarch like the UK currently does with Canada etc. Cromwell's invasion of Ireland had nothing to do with Scotland or Scots. Within a short time, after the Scots proclaimed Charles II not only King of Scotland but King of England too, Cromwell invaded Scotland and the country was forcibly unified with England though only for a relatively short period. It may be likely that some colonising of Ulster by Scots went on during Cromwell's occupation of Scotlad but it certainly wasn't the main period for it. The two big periods were early in the century in the initial wave and again later in the 1690s during the "ill years" when massive numbers of Scots fled the series of disatrous famines in the country.
