Hi Elena, nice to meet you. Welcome to WikiTree :)
I checked your Contributions list and found where you had uploaded your GEDCOM file.
Currently you are on step # 2.
Your GedCompare Report is ready for you to view and manage: https://www.wikitree.com/index.php?title=Special:UploadGedcom&action=review&gu_id=91819
Just follow the prompts and instructions and everything will work out great. You can select which ancestor profiles in your GEDCOM match existing profiles on WikiTree so that those can be skipped and no duplicates are created. When you feel the report is ready and all criteria listed have been met, then you can submit the report for approval from WikiTree. After they approve, then at that time you get the final decision whether to create the profiles here or not.
After importing, you can connect those profiles to your own.
It is even easier than it sounds, and well worth the energy invested.
I hope this is helpful. Please let me know if I can do more.
Have a super day!
