The best way to trace your "Boyce" heritage is to start with your parents and go back in years to your grandparents, great grandparents etc. As you work that you will find siblings and more information about their spouses etc. which will in most cases add new surnames to explore!
If you already have some relatives you could start to add them as you build your profile once you are confirmed as a full member. But in order to do that you would have to finish the process of filling out your tags and clicking on Volunteer button as explained in the initial email. Once you do that you will be confirmed by one of our friendly greeters!!
Here's how to do the Tags:
You may want to add some tags on your page indicating a family name for one tag and a specific location like a country, state etc you are interested in, for another tag and then add other surnames or locations as tags as desired. That way you will be connected to others with the same interest.
Click on http://www.wikitree.com/wiki/Special:Following to add or remove tags. Be sure to add comments explaining why you're following the tags. Those appear on your profile too.
Once you are a full member you will also receive weekly emails with help pages to get familiar with the inner workings of WikiTree.
Hope this helps!! Dorothy, WikiTree greeter.
