https://familysearch.org/ark:/61903/1:1:FH1Z-CLB shows an indexed name of Sophonia Graves for the parents of Elijah Graves, when it seems to be Tyhhonia, or something similar to that. Is there a way to fix it?
If you hover over "Edit" on that index, you will see "Edit Unavailable."
Editing is relatively new on FamilySearch extracts. More are becoming available to edit all the time. I'd check back in a few weeks or a few months, and it may be available to edit by then.
As Julia often says, the index has done the job - you found the record. The index is a finding aid, not the record.
@Áine Ní Donnghaile That's a good point, though I'm not the one who found the record. I actually almost removed it before checking the record itself.
