When indexing Deed records I am seeing the word "do" in the Grantee column where you would typically see the last name. It is not a last name because it does not have a capital D. I am seeing it after several given names in a row.
It would help to see the batch with the batch code.
It looks like you are seeing Ditto marks, this article may help you to discern about signs of repetition:
If a record has a ditto mark or other sign of repetition, type the corresponding information from the previous record or field. Do not index the word "ditto" or the ditto mark itself. Other signs of repetition may include the abbreviation "Do" or a vertical or horizontal line.
Note: Sometimes you will have to depend on contextual information to determine whether a mark indicates repeated information from an earlier record or field, or whether it means something else, such as that no information was given for that record or field.
Hope this answers your question.
Yes it is Ditto. Thank You
