The city directories need a great deal of work done. There are many, many people missing entirely and many people have only a first name or a letter. Many names are merged into a business name or street name. I really wish ancestry would find some way to let us help upgrade this. At least with a first name you can add a correction but when they are missing entirely nothing can be done to improve this database. I just saw a page with at least seven people missing entirely. I stopped ancestry for many years and have come back and this has not changed in years. Will it ever?
And again there are pages with pictures on them where many people are shown and few names are mentioned. Users can help with this if there is a method to do so. Facial recognition at a later date could be used to confirm or deny our alternates. Or maybe this will even help with improving the facial recognition part.
