I signed up to Ancestry, but found it a bit difficult, because on my fathers side the eldest sons were all named John Sutcliffe, going back hundreds of years and on my mothers side, my Grandmother married her cousin. I found it quite confusing and gave up but I would like to have another go!
You will find in most families the son always had the same name as the father down the generations. I then add their year of birth to their name, so John Smith 1838 is the father of John Smith 1864 for instance. It helps.
Don't give up! Research a family with a more unusual name first, which should be easier, and save the more difficult ones for later when you are more experienced. Every problem you solve adds to your knowledge and helps you next time.
Collect the census returns and study them because they give you a timeline for the family and also the names of siblings which can be important. The lives of family members are often interwoven with each other. Your filing system is critical! Name everything carefully i.e. '1881 Census John Smith' comes before '1891 Census John Smith'. I always name my documents with the year first then everything sits in the right time order.
