Andrew, just saw from your later post on finding more of this family since this morning. Glad this matched up for her, I may not have found her either if I wasn't just in the Philadelphia death collection a while ago, I tired there first and she came up. Tuberculosis was very prevalent in the 1800's and worse in cities or populated areas. She was so young, it's so sad and ironic that her daughter survives through her mother's disease only to die young of another one.
The note on the record page on FS says "resided 4 yr in Phila", I should have put that link in for you too it's here if you need it for what is at the bottom of the death record of which I can't make out all the words either - " ? of New York, married, four years ? in Philadelphia."
