Hi Diane, and Welcome to WikiTree!
It looks like the profiles of interest are already connected on WT but could use additional sources to back this up. I feel the links you've provided are helpful clues and may be invaluable to finding more robust genealogical sources. I think what I would do is temporarily move the links you have from Sources to a new Research Notes section and indicate the date that you last viewed the web site. Then you could also consider transcribing/copying & pasting the same information currently visible at the cornwall-opc-database.org site to the WT profile's Research Notes section as well. Once that is done, removing the full link as the linked site indicates is surely a good idea as Ros points out.
Writing about this gets wordy very quickly! If you'd like me to update one of the mentioned profiles to be the way I'm thinking, please let me know and you can take a look. And, if you really don't like it, there's an easy way to undo my edits and revert back to what you currently have.
Hope that helps.
