Sorry, I do not know oa any Island the Allens lived on. Isle of Wight is a County in Virginia taken fron Surry County. There are a lot of Allens that wish to connect to Arthur of Beacons Castle. His line was searched with the death of William of Claremont. No descendants with the Allen name were found beyond him. The heir was William Oegain who was a descendant in his family that changed his nameto William Allen. E-mail me for more info on this or other Allen lines. Broddy's Books offer about the best research on these lines as you can find.
