Valid XHTML 1.0!  Valid CSS!  Bobby WorldWide Approved A

This site conforms to the W3C's WAI Accessibility Guidelines, Level Single-A. However, it also implements the majority of recommendations at Double-A and Triple-A levels.

The code is valid XHTML 1.0 and valid CSS2. All Javascript elements are non-essential and the site is fully functional without scripting. All links will open in your current browser window.

If you have any problems accessing this site, or any other technical difficulties, please contact us by e-mailing

Please note that the family tree page on this site is compliant in theory rather than practice, since the complexity of the information means that the text must be included within a graphic and may therefore be difficult to read. However, all of the essential information is also contained within the portrait gallery. If an effective means of constructing and displaying family trees for display in a web browser does become available, we will recreate the page.

Please also note that due to the current limitations of Microsoft's ASP.Net technology, the search page on the site is not currently standards-compliant. As soon as ASP.Net supports XHTML fully, we will ensure that the search page meets the same standard as the rest of the site.
