Welcome to RC Andy,
I think your best bet is to trawl through the Tech site here, as there are (and have been many of us) who have this query.And go to the Moderator's boards which give links to pages on here and on the Web.
Are you looking for a Free Family History programme to download? Yes there a number of them which have been reccomended by members.
Free search sites to find information ,then there are many also.
I have subscribed to Ancestry. co uk for a couple of years and though it took ages to take the plunge, i have found dozens of Census returns for my family.
Genes I have been on for years and just about all of my (now 4,000+ ) relations have come from contacts on that site. There again you have to be very careful about the intial contact(lots of comments on here in the Common Room)
have a look at some of the links here and you will find some help. Don't forget that you can also send a message to even some of the oldest queries! And also ask someone to do a "look up" for you.
Regards Spring
