Stirnet Genealogy
Families Database http://www.stirnet.com/HTML/genie/genfam.htm
This has a huge amount of information on hundreds (and rapidlyincreasing), mostly landed, families in 3 categories listed below. It ismore "user friendly" than most in that it shows many generations on onepage.
I - Ancient & Mythical
II - Continental Families - Medieval & Renaissance
III - British Families - Medieval, Renaissance & Modern
(Note they also say "We will soon be offering CDs of the database forsale at a modest price.")
