Have you ever wondered just what your ancestors were doing in the medieval or Tudor periods? If you have taken your family tree back to 1600 with parish records, the censuses and BMD indexes, it is entirely possible to go back further. Issue 4 of the Discover Your Ancestors bookazine is available now, which includes my article 'Back to 1066', which sets out the most important records and how to use them. Who knows, perhaps your ancestor sailed for England with the Conqueror in 1066, or fought at Agincourt? Alternatively, were they hauled before their manorial court? With a lot of hard work and a bit of luck, you can take your family tree back deep into the medieval period.
