We want to hear which websites you use for family-tree research.

Which genealogy websites do you use, and why? What do you like about the site, and what makes it so useful? We're looking for sites both well-known and obscure, provided they are an effective and reliable genealogy resource.

Add your favourite sites, and why you'd recommend them, to this PC Advisor forum thread or email them to [email protected] to be in with a chance to win our Readers Sites prize.
