Hi Sharon,
If you are relatively new to this family history / genealogy (addiction!

), you really need to go back to basics:
Start here -
Genealogy FAQ
How far have you got with your Dad's research?
His Father, his granddad? His Great granddad?
Have you birth, marriage and death certificates?
These are a must have. Please do
not rely on names and dates on the internet. By all means use them as a guide - but you
must get the written evidence, which are mainly certificates (B.M.D) and census transcripts.
All the best in your research Sharon.
regards,
Dave
