There are some excellent medieval and Tudor sites on the internet, here are just a few:
Archaeologist and historian, Ruth E. Richardson drew my attention to her site. She is the author of 'Blanche Parry Queen Elizabeth I's Confidante' and carries out research into Blanche, who was a childhood companion and later gentlewoman to Elizabeth I. The site provides interesting information on this little known Tudor figure.
Slightly different from the usual medieval and Tudor sites - the website and blog for 'Shakespeare's Queens' which is showing at the Arts Theatre, London, as part of 'Double Bill' during October and November 2012. I would definitely recommend the show which involves a posthumous argument between Elizabeth I and Mary, Queen of Scots, with the rival queens illustrating their points with the help of William Shakespeare and his queens. Look out for it if it ever comes to a theatre near you!
The Hounslow & District History Society have a new website, advertising details of the Society's activities. Local history societies are a great way of meeting like-minded people in your area so, if you're local to Hounslow, why not come along to one of the Society's meetings? I'm not a member, but gave a talk to the Society in September 2013 on Anne of Cleves.
The Post Office Shop blog is well worth a look. Here's the link to their article commemorating the life of Queen Anne, who died 300 years ago.
This a new site which provides a free service to both tutors and students. It helps students locate tutors in their local area for a variety of subjects (including History). I haven't used this site, but it looks interesting and is worth a look if you are seeking a tutor.
This website was brought to my attention recently (January 2015). It's a fantastic resource for anyone looking to trace their US ancestors and I well recommend a visit. Use the site to help you find your ancestor's obituary, with records categorised by state. You can then browse through the newspapers listed. If you have US family, do take a look!
This is a new site, which looks at secret history stories - stories that are not well known from history. It is well worth a look.
