Since you appear to manage both profiles you can merge them together, no problem. Just complete the merge proposal and a page will come up with directions. Wiki Tree's Help: Merging explains the process in detail (it actually takes longer to read the guide than perform a merge ). If visual aids are more your thing, WikiTree: Merging Profiles on YouTube, while an older demo, shows the basics.
You will have a chance to preview your merge edits with a preview button - just like those on profiles. I always use it to review merged text. Barring all else, of you mess it up, it can be reversed, so no freak out necessary. Try it and post comment for help if you need more guidance.
