Data from FamilySearch.com

I recently joined geni.com and have been uploading a lot of data. I met a relative that has loads more data but has put it all on the mind map app called "Mindmaple". I also found some information about another branch of the family from Scotland on familysearch.org so I'm also wondering if there is a way to merge other sour es with geni.com

so cool cousins histories

There is a complete ancestor tree on Wikipedia. Go to https://www.wikitree.com/wiki/De_Beer-1028 and click the green "Ancestors" button. For his wife, not so much, but I am sure it will take only about a half dozen connections to also get her complete tree.

Hannelie the only way is by adding manually one by one. While doing so you will most likely find mistakes on Geni and perhaps FS thst you will be able to correct as you go.
Best regards
Ps i personally don’t care for Geni because there’s too many highjackers that prevent you from making corrections.
I also use FS
