Can you provide a citation for the book these pages are taken from?
This looks like a couple of pages from some unknown book. I would put this under Research Notes or add an "External Links" category since there is no documentation and we don't know what the original source is. This merely states that John Prichard is the father of Roger but provides no evidence.
Aside from Roger's parentage, the information in this link is pretty much the same as what is included in the cited sources on the profile.
