It disappeared a couple of months ago, leaving a few hundred broken links.
It has a collection of several hundred bios of Tudor types. (Some of them are lifted from History of Parliament.)
It also has a collection of medieval English genealogy mostly culled from Burke's and the like. Often with spare spouses and kids that other sources don't bother to mention. Also not particularly immigrant-orientated, so covers families that other sites don't reach. But all the common errors and fakes, so not an authoritative source.
