No idea who she is, but I gather she was from Canton, Ohio. Even though the photographer’s imprint is damaged, I can make out a C and then an O followed by a period. Since I have other photos from Canton, Ohio, this was my immediate thought.
Searching on the name Vignos in the US censuses, I found an Augustus Vignos in Canton, Ohio, although the occupation had nothing to do with photography, nor did that of his son Alfred. But, apparently, the business they ran, although it dealt with cutlery, also included photography (see the following PDF document that someone put together about Augustus, his business, and photography).
And of course, once I’d already written this post and went to set my tags, I saw that I already had one for a photographer “A Vignos.” And wouldn’t you know, it was from Canton, Ohio.
Now that I look at that I take a look at the other photo, I wonder if they are the same person, #152 being a younger Theodosia Currier. Hmmm. What do you think?
