Julia Octavio Potter, Lowell Mills, Massachusetts, 1845

When I toured the Lowell National Historic Park last May 2013 (Lowell, Massachusetts) I found this posted mention of Julia Octavio Potter who signed a protest petition on 15 Jan 1845. Hopefully someone reading this post will recognize her and contact me to identify her. I thought that "Octavio" was a most unusual middle name and must be/might be a good clue?
