I did the research and you don't need to look in Kentucky.
A family tree posted by judeelynne:http://trees.ancestry.com/tree/28540258/person/12188413771?s...
identified the father as William "Bill" Matison Pennington, born 26 June 1879 in Martinsburg, Elliott Co, KY, died 16 Oct 1940 in American Falls, ID. He married Cynthia Rowe(or Roe) on 24 Dec 1903. They had children:

--Jessie Merle or Muriel Pennington Sparks, male born 17 April 1911, in Elton, Langlade, WI, died 7 Feb 1969 in American Falls, Power Co, ID.
Cynthia died June 1911 in Elton
--Another tree indicated that Mary was in Victoria, Victoria Texas in 1972, her husbands last name was "Wofford."
The 1910 Census of Evergreen, Langlade Co, WI, owned the home.
William M. Pennington, age 31, born in KY to father born in Kentucky, mother in Virgina, Teamster/Lumbering, married 6 years.
Cynthia, 31, born in KY, mother of 3/3 living
David O, 5
Virgie L, 3
Mary A, 1 1/12. The Census was enumerated on 26 May, so if correct, Mary was born about April 1909.

The 1930 Census for American Falls, Power County, ID
Genevieve Woth(as transcribed), age 50, born in Ireland, Widow.
She had two roomers, neither was Mary.
-----Mary G. Wofford-----
One family tree owned by a LindaKolar, identifies a Mary G. Noth, born 14 March 1910 in Louisville, KY, dau of Richard F. Noth and Genivieve O'Donald as being married to a Wofford, death in Victoria, TX.
--this is all the information shown. So, basically there is NO proof to connect this Mary to the Noth family, or to being the correct Mary Pennington. I am leaving this "connection" for you, but I would do a lot of research to prove/disprove this person before accepting it.
--The Social Security Death Index shows a Mary N. (Noth?) Wofford, born 14 March 1910 [the 1910 Census "indicated" a March 1909 date for Mary Pennington] died 14 Nov 1996 in Victoria, Victoria Co, TX. There is NO PROOF this is the correct person, additional research MUST be done to prove/disprove. This person's SSN 451-24-8915 was issued in Texas before 1951.
Public Records show Mary N. Wofford, born 14 March 1910 at 2404 E. Colorado St, Victoria, TX. Also at this address is Herman H. Wofford, no DOB shown. Both of them also at 214 Monterrey Dr, Victoria, TX.
Here is a book that might identify some further information. It does identify Mary adopted by Dr. Richard Noth, but little additional online. It is from the Pennington pedigrees, Volune 35-36 from the Pennington Research Association:http://books.google.com/books?id=IVxVAAAAMAAJ&q=%22richa...
I'd first attempt to obtain the obituary of Genevieve Noth. She would be the most logical to have Mary identified. Genevieve died in 1961. If Mary is not listed, that in itself does not mean Mary had died. I'd suggest you first contact the cemetery where she was buried, it might have some records, and would be the quickest search. Then, try the obits of her siblings.
American Falls is a small town. The local library "might" be able to help. Most libraries can not do research, or research for person out of town; but, it's worth a try. http://library.public-libraries.org/Idaho/AmericanFalls/Amer...
The Power County Historical Society and Museum. They "might" be able to help. But, if they have a museum, they are probably more dedicated to it and collecting information. Once you find the Noth family, they'd probably be interested...but give them a try:http://www.co.power.id.us/index.php?option=com_content&v...
I did find the American Falls Press (newspaper) online, but there is no issue for 1922, 1961.
