The alternative genealogy of Wilke is not quite so unsatisfactory. This has John born in Yorkshire around 1623 and dying at an undetermined date in Nottinghamshire where his father came from; while Roger is born in Westmeath, Ireland around 1650 and dies there around 1701. It is compatible with John settling in Ireland, and Westmeath is where the Norths did establish themselves. On the other hand, it presents no connection with the Lords North of Guilford, who are believed to be ancestors of the Irish family in some way - http://www.bomford.net/IrishBomfords/Chapters/Chapter16/norths_of_i...
That web page presents a genealogy of the Norths starting from John, with Roger having sons Joseph, Caleb, Elizabeth, Roger, Susanna and Mary, of whom Caleb and three others come up in the Wilke and Fleischer genealogies, and Caleb alone in the Plunkett genealogy. So the problem is not Roger, it is his ancestry.
The page http://www.bomford.net/IrishBomfords/Chapters/Chapter16/Images/coff...
reproduces a magazine article which gives fuller information on the North settlement in Westmeath.
I am hoping that those who contributed parts of this story may be able to give some sources which would enable this mess to be sorted out, and since there is a “master profile” attached to John North the curator advise how to reorganise the records. I have derived my genealogy from the Bomford site above, down to my ancestor John Roger North (c.1787-1853).
The Lord North family seems to be as follows, based on Wikipedia (W), thepeerage.net based on Burke’s Peerage (B), and The Life of the Right Hon. Francis North, Baron Guilford ... (N):

None of these Norths is mentioned in any of the three sources as having any Irish or American connection.
