Family Search added Maria Szrogi LDZ9-2F6 baptized Aug 26, 1821-how can this be deleted?
The 1821 baptism records for Jakubany, Stara Lubovna, Slovakia shows these line items: Line # 67: August 20, 1821: Maxim baptized, son of Lucas Szrogi and Helena; Line #68: August 26, 1821: Anna baptized, daughter of Basilius Katrenits and Anna; Line# 69: August 26, 1821: Anna baptized, daughter of Stephan Borodacs and Anna.
I think that whomever submitted the Maria name, this is fictitious and may have converted the Maxim name to Maria, used Maxim's parents names and used the baptism date below on line 68 as the baptism date, as line 67 clearly shows the baptism date of August 20. For this reason, I think Family Search should delete LDZ9-2F6 as someone who doesn't exist, since I can't delete that factitious person. Yes, I could change the relationship so I don't see it in the tree, but it will stay out there and someone might waste their time doing ordinances for her.
I suspect that you are decades too late worrying about spurious LDS rites for this Maria, because her profile is based on this indexed baptism: https://www.familysearch.org/ark:/61903/1:1:KHDM-7KP.
By some mysterious-to-me process or reasoning, many of the entries from the older baptismal indexes -- such as the Slovakia church books -- were entered into a previous system on FamilySearch, following the index (and all of its errors) letter-for-letter exactly, and creating separate new profiles for each person involved (child -- usually daughter, in my experience -- and parents). These profile sets from that previous system were then imported into the then-brand-spanking-new Family Tree a decade ago, and have been floating around in it ever since, until/unless someone comes along to clean them up.
The register image where Maxim appears is not available online, because it's a multi-part film and there is something that's restricted in one of the parts. If you've nevertheless gotten hold of the image, and you are certain that your reading is correct, then you're well-placed to clean up this floating twiglet. The best way to do so, in my opinion, is to attach the indexed baptism to the "Maria" profile, edit the source citation to note the error in the indexing, edit the profile's sex to male, and then either merge it with Maxim (if he has a profile), or correct the name to Maxim. If a merge is involved, you'll probably also need to merge some parents.1
The remedy @Julia Szent-Györgyi describes is the one I use.
There must be many millions of these 3-trees brought in from the previous system. Cleaning them all up is an a very tedious chore, and I can confirm that if they are just left drifting out in the public tree space eventually someone will find them and do something to them. Unfortunately the result usually isn't good. Thank you for helping to get these relicts squared away, @Cieslak Ron.0
