Hi,
I haven't tested their US records, only the British one, and that seems *good coverage for England and Wales only (*excluding Scotland) .I am not a paid up member to them and have never have been , I just receive emails from them( I must have joined their site at sometime to receive emails from them way back).
Online Free Censuses for England and Wales without having to join up (ie provide email address ect, or credit card details) is a very good promotion/offer.
I don't need to use it myself as I hold a world sub with ancestry, but thought it would help many people out.
Kind Regards
