For anyone who wants to explore their possible line to Charlemagne but is not working toward pre-1500 certification, one approach is to create a free space profile attached to your own profile for your own use. On this free space profile list the line of descent you have from Charlemagne to yourself. Then provide links on your free space profile to all the profiles that currently exist on WikiTree. Now you will see the gaps in the line that either need to be filled, or which disprove the line. Without being pre-1500 certified, you can post questions on G2G with respect to each gap, such as (this is made up!) "Wikitree profile Jones-1234, born in 1522, shows no parents currently. I have her as the child of Jerry and Josephine Smith, born in Wichfield in 1483. The source can be found at British Archives, www.archives.yes. Would someone be willing to create the profiles for Jerry and Josephine Smith?" I'm sure you'll find people willing to help if you work profile by profile in this way.
