Hi Neil and welcome to Wikitree!
Have a look around the site and use the search page. It can be found under the Find drop down menu.
When you are ready to add your family branches, you will need to upgrade to family member. It is free to upgrade. If you have any questions about the process, check in with your greeter.
I'm sure you will find lots of resources and fellow researchers here on Wikitree to help you with your research.
Enjoy your journey into the past!
