For others who want to look at this, the record is at https://www.familysearch.org/ark:/61903/3:1:S3HT-6W39-7WY?i=3
These slave schedules do not enumerate the owners - so the first line with Telitha's name refers not to Telitha herself, but the first of her four (not three) slaves.
The B stands for "black", the other letter is an "M" that stands for "mulatto" (i.e., mixed race).
I think it is Octoroon (1/8th black).
