If you are interested in a more detailed picture of the names and name patterns present in this document, it is available in my article Names and Naming Practices in the Merioneth Lay Subsidy Roll 1292-3 . The names are arranged in order of frequency, from most popular to less popular. If more than one spelling was common, the most typical are listed, again in decreasing order of popularity. The following 53 names had at least five examples in the list. These 30 names are all those about which there is no question of interpretation.
