Welcome to Wikitree, William! You can use the search box at the top of your profile to search for your family. Start here:

You can use the search box other ways. You can search for an individual or you can use the wild card (*) in the first name field to find anyone with that surname. Then narrow your results by date or location.
Come back here to the forum if you have any questions along the way.
