There is a Michael Heinlein GKV4-71T says born Germany 1841.
Says he had a child, Michael Heinlein born 1843 GCXT-YVL
That can't be...the father, Michael, would have been 2 years old.
Hoping the person who added this record will see this message.
@IMA777 It's unlikely that the person who added that record will see your post here, since only a tiny fraction of FamilySearch users frequent this Community.
However, you can examine the change log for the son at https://www.familysearch.org/tree/person/changelog/GCXT-YVL . There you can find the entry on 19 April 2023 where a user added the son born in 1843 to the father born in 1841. You can click on the username in that entry and send that user a message via Chat asking about this change. They may or may not reply, but that direct communication will have a much better chance of being seen than your post here.
If you don't hear back from the person who made the change, you can remove the parent-child relationship that seems incorrect. Or you could simply remove that relationship now, providing your reasons for the removal.
Thank you for your help
The contributor who added that information copied it straight from the 1900 census without looking at the census page. The extract shows Michael, age 59, with a son Michael, also age 59. The error in the extract is probably an artifact of the problems that occurred with the 1900 census indexing a few months ago. There is no son Michael listed on the census image.
@N Tychonievich are you still looking after the 1900 US Census index issues, too? Thanks. https://www.familysearch.org/ark:/61903/1:1:MSLX-KBJ
