If Dale is interested, there is a site on Rootsweb dedicated to the Perrott family of Pembrokeshire and its offshoots. One of the links is a book published in 1882 called "Perrot notes: or some accounts of the various branches of the Perrot family". It's a bit romantic, of course (the author can't quite bring himself to deny, nor fully endorse, the Henry VIII story); but very well researched and has a lot of information.
One predictable result to be found on the Rootsweb site is that lots of people have tried to find a link with the John Perratt of Virginia, and no-one (yet) has succeeded. There is apparently a Barbados branch (?? from John Perratt the Quaker) which seems to have used the Perrot coat of arms (three golden pears) on at least one occasion. But whether they were entitled to, I'm not sure that anyone knows. (Two branches of the family lived in Northleigh, Oxfordshire, and seem to have hated each other. One of them persuaded a herald, at a period when the heralds were notoriously corrupt, that the other branch were only descended by an illegitimate son, so they could only have their coat of arms as three silver pears, not gold. All subsequent researchers seem to have concluded that the second branch were perfectly genuine legitimate descendants; and they got their golden pears back after the first branch died out (for reasons like "eating crabs", or "regret at shooting a favorite servant"), I posthumously award them a fourth golden pear for apparently being ancestors of Jane Austen.
