Hello,
We are winter neighbors in Charleston, SC. My 11-year-old daughter and 9-year-old son go to Buist Academy in downtown Charleston where they are members of Warwick house. The school uses a house system to integrate the grades and the houses are named after European castles. We took our children to Warwick castle last Christmas and my daughter fell in love with Æthelflæd, She went as Æthelflæd for Halloween this year. There has not been much mention of the Warwick burh in the Saxon series to date but I am sure you would be a delight if you are ever interested in talking to the children (and their parents:)) about what you know of their house history.
Thank you for the great books,
Aspen Olmsted
