Hi, Mark
Thank you for being a Guest Member on WikiTree. Check out the Membership info and consider upgrading. WikiTree is always 100% free, and you might find many cousins in WikiTree to help you add profiles to the one-world tree.
At the top of your profile page, you see SURNAME entered. Click the magnifying glass, and you get a list of all SURNAME profiles on WikITree, and you can sort alphabetically or by birth or death dates to see if family members are already on WikiTree. Your 2x gg may be here. You can repeat this with each surname you are researching.
I hope this helps, and if you have any questions, don't hesitate to reach out.
Welcome! We look forward to working with you!
