Thank you, Bronwyn. She was very sick. Now I pray that she has peace.
I have added my DNA information to WikiTree as well. I did that some time back.
We don't have to upload the DNA here on WikiTree. We just tell WikiTree where we tested (or in your case, where your 95 year old tested). If we have a GEDMatch kit number, we add that information, too.
Here is the path to add that information to WikiTree:
Have him go to his profile page. Up at the top right of the computer screen, he will see his last name and Wiki ID number. Click that, then click where it says DNA.
When that page loads, there will be a link that says "DNA Tests" just under where it says in big bold letters, "DNA Ancestors View for (his name)". Click that "DNA Tests" link.
When the next page loads, there will be a place to add the DNA test information. He will click the dropdown arrow where it says "Click here to select DNA test" and then click on the company that he tested with. Edited to add: Then click "Add Test". (Sorry that I missed this part the first time.)
After that, it should open a page that also has a section for the GEDMatch number. He can click the edit button on that page and add the GEDMatch number if he has one.
Then, he needs to click save.
Would your family member in the other country be able to do that? I hope that my instructions make sense. It is usually easier for me to do than to tell. :)
