Deletion of Margaret Brown (criminal)

Comment: Several of the "delete" !votes  are basically  or "So and sos are inherently nonnotable", ignoring the 168 word article about her long criminal career in the 1884 NY Times and the four book references.The one JohnZ presents http://books.google.com/books?id=ZrAXAAAAYAAJ&pg=PA375&dq=%22Mother+Hubbard%22+%22Margaret+Brown%22&output=html is definitely substantial coverage, stating that her face is familiar to detectives of every large country in the U.S. I have now located a copy of the 1929 "Gangs of New York" and will check it when I get hands on it for the extent of coverage. Per Google Book Search, under her alias "Mother Hubbard" she is discussed in "The American Way of Crime" (1980) By Frank Browning and, John Gerassi," page 283 along with her criminal associate Black Lena Kleinschmidt. She is mentioned in  "Women, Crime, and Justice" (1980), by Susan K. Datesman, Frank R. Scarpitti, page 193, in "The Professional Fence" (1974) by Carl B. Klockars, page 176, and in "Crime and justice: V.1" (1977) by Leon Radzinowicz and Marvin E. Wolfgang,  Page 312
