I think we have some different people mixed up in these records, or at least the ones attached to this profile as sources.
https://www.geni.com/photo/view?album_type=photos_of_me&id=6000... -- this refers to a John Harlaw of Montserrat who is the son of Alexander Harlaw of Abderdeenshire. A Scottish family would fit with the history of the island and also the history of the Harlaw name in Aberdeenshire. Montserrat was one of the places Scottish Catholics went for refuge, so that would make sense. The record doesn't support this profile or its paternal ancestry.
https://www.geni.com/documents/view?doc_id=6000000017431878002& -- this refers to a John Harlaw or Harlow.
https://www.geni.com/documents/view?doc_id=6000000014558262001& -- this refers to a John Dionis.
I'm not seeing how we're combining a Scottish Highlander and a man named Dionis to get a Joao Moises Dionis Benabides. Where is the connection happening? Or are the attached Harlaw/Harlow records here erroneously?
The Wikipedia page on Caribbean Jews mentions a "Joao Moises Benabides Dinis, (a/k/a Juan Dionis)," but it's uncited and there's no page on this person, so I don't know what to make of that.
