What Happened to Georgiana Winchell?

I've been working on a family mystery tonight, what happened to Georgiana Winchell.  She was  born 21 September 1849 in the Town of Great Barrington, Berkshire Co., Mass.  Her parents were George Winchell and Sarah Livingston.  Sarah died 24 September 1864.  On the 1865 Massachusetts census, Georgiana was living with her sister Rachel and her husband William F. Boyes, along with her father, in the Town of Great Barrington.  George died 17 August of typhoid fever.  In 1870 Georgiana is not living with Rachel and William, although they have a daughter 4 years old named Georgiana. 

I recently found a census record that lists Georgiana Winchell of the right age and birthplace living with I.N. and Mary Pardee in Susquehanna Co., Penn.  According to Clark Pardee's marriage record, Mary's maiden name was Winchel and her middle initial was L.  She is the right age to be Georgiana's sister who has been listed as Lucinda.  I've never found a trace of Lucinda either. 

Ira N. Pardee was a clergyman.  According to the 1855 New York census, he lived as a child in Kingston, Ulster Co., NY.  In 1880 he and his family were living in Webster Co., Iowa.  Georgiana is not living with them.  By 1893 the family is living in the Cortland area where their daughter Eva became engaged to Harold Chester Peters.

Now I have an additional question to answer as well.  Was Mary L. Winchell the same person as Lucinda Winchell?
