Hi Brian
Do you want to know how to start finding out about your family?
There is only really one way to do it. Start with with what you know for sure - yourself, parents, grandparents etc. etc.
Are you in England? Your full birth certificate will show your parents names. Then you will need their marriage certificate which will show when & where they were married, how old they were and, their father's names and occupations etc..
You might already know where your parents were born - their birth certificates will show when/where they were born and their parents names.
Once you have (you may already) somebody who you know was born prior to 1901 then they can be looked up in the census records - every 10 years back to 1841.
There is lots of useful information on the beginners board here.
Just post on here exactly what you want to know and then somebody will advise you how to find it or .................... maybe even find it for you! Just post names, dates, places - everything you know and it will help everybody to help you. You will get lots of help and advice on here!
Good luck and happy hunting
