I offer no guarantee that this pedigree is genuine and accurate.
It has been found on the internet and I have no reason to doubt it other that the normal doubts that follow every internet discovery. Establishing a source confirmation is the golden rule of all genealogy, but no matter how strong the evidence is we must always question the accuracy of every claim.
If it was compiled by the Collage of Heralds it stands a good chance of being authentic and accurate but it is still prudent to question it all.
