h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

I have a special interest in John Perrot the quaker,in as much as back in 2005 I was involved in a television program made by R T E the Irish Television Station, which followed the travels and travails of the afore mentioned John. We filmed in Ireland,Rome and London, the show (called Black Sheep)finished with me speculating on whether I had a claim to the throne of England. As a result of making the show I became interested in my family tree and can trace it back to Bandon Co. Cork in the early 1700s. I am trying to bridge the gap between my ancestor Richard Perrott of Bandon and John Perrot's family that he left in Waterford when he went preaching.any one out there got any ideas?
