Lazlo writes about European High Medieval history (12th Century and 15th Century), especially settings in France and England. (Having been a keen genealogist since the 90s, he has traced his family back to a 13th Century Knight in Burgundy.) He occasionally posts free resources from his research, such as the 1550 East Sussex Lay Subsidy Rolls and excerpts from the papers of Etienne Baluze here.
For now, take a look at the East Sussex Lay Subsidy Rolls for 1550.
Or the papers of Etienne Baluze.
