grand father birth date is 1040 (LKMH-C4M) and grand son is 820 (L63N-MB9)?
I understand that you do not want to make the changes on those records but you would like to contact the person who made the error.
We logged into FamilySearch to the record of Raoul D'Ache L63N-MB9. We scrolled down to the vital information and clicked on the name Mia Schaber, who made the post 8 Dec 2013.
Please log into FamilySearch. Go to his record, then to vital information as we did and click on her name. You will see that you can message her through FamilySearch. Our message system is confidential and once you send a message she can respond to your message. If she does, you will see a little red dot at the top right corner of FamilySearch next to text message icon. You will be sending the message through FamilySearch, not through Communities so the answer will come through FamilySearch.
If she does not answer you, and you know the correct dates, we recommend you follow the instructions given in other posts to make the correction yourself. Please be patient as the other guest may not see your message right away.
Thank you so much for your question. We hope this answers your question about contacting the other contributor.
We assume your are asking how to edit the dates and enter your correct dates. Here is a link on how to edit vital (birth dates, etc) information. We are also including a link on how to edit parent/child relationships.
It might be wise to get some sources, for Henry D'Ache' and Roaul D'Ache, to be sure they are as accurate as possible. When we searched the internet for them, we found a movie about Henry, and several statues about Roaul, but that may be for a different Roaul, because the dates are way off.
In addition to the previous comments and as mentioned about sources being found and added to confirm information, you may also find the information to be useful that is at the link here, including the Related Articles near the bottom of the linked article: https://www.familysearch.org/help/helpcenter/article/when-i-am-searching-historical-records-what-are-the-best-practices-and-tips
I am new here and i don't want to change anything but tell to the person that made that tree part that there is possibly something that is not completely exact. If there is no way to reach those persons I will chack otherwhere but i am only tracking what is available to complete my familly tree.
This is about the answer I was looking for.
On the other hand, I find the system a bit too easy to destroy. If anyone can make new material without any verification (and this one could be made automatically with a program). it can attract others to discredit the system and suggest you, to use another platform...
I found many good links here and I like the way things are presented. It would be a great loss to see that go away because there are too many inconsistencies.
It would be also nice to have someone official in support for those questions that would be able to verify everything.
Anyway, I am still building my family tree and I am trying to draw it on AutoCAD. It will produce a huge drawing of about 5000 names (according to my first estimate). I am still working on the "inserting name" part and I have already more than 2300 names. Many branches are done but very long ones are not all populated already.
I'll keep going and see what I can do.
Thank's for the answers.
