Is it possible to undo an edit to the 1850 census?
I made an edit to the 1850 census <https://www.familysearch.org/ark:/61903/3:1:S3HT-6XG9-G52?i=218&cc=1401638&personaUrl=%2Fark%3A%2F61903%2F1%3A1%3AM88G-CTV> for John B Watts <https://www.familysearch.org/tree/person/details/2QB1-WVM>.
His surname had been indexed as "Walls" instead of Watts. Before I saved the edit, I checked the box that said something like "Select all" or "Apply to all" thinking that it would update the surname for him and his daughters on Lines 13-17. However, the edit combined his daughters' names into his, so now the source linker (?) is unavailable for his daughters' records <https://www.familysearch.org/search/linker?pal=/ark:/61903/1:1:M88G-CTV&id=2QB1-WVM>.
Will you please help me?
