The websites you need arehttp://www.findmypast.com/welcome.jsphttp://www.1901censusonline.com/
tracing maternal lines is tricky though, because the surname changes on marriage and you need to know what the maiden name was - sometimes you can be lucky and find a census form with a brother on it to give you the name, or you may have to order a marriage certificate, which will give you her fathers name
also try googling some of the names with a town or village name - I've traced my fathers family tree recently, there was one bit we were completely stumped on and just out of desperation I googled the name and the address and actually came up with a whole website of another family tree and found out that the male relative in question was taken to the poorhouse and the rest of the family moved in as lodgers with another relative
That'll give you a good start
depending on what subscription you have, you may also be able to look up who is living in the neighbours addresses, and if its the same family today, you could write and ask them if they know anything
Have a play on those websites, it'll all make sense when you're in the middle of it.
I also found, initially on findmypast that I was buying credits for x amount of searches... if you pay for anything, get a 6 month subscription as when you start you follow up a lot of blind leads, and it works out cheaper to be able to look up everything you want for 6 months than to keep buying more credits
