How Many Members of Joseph Smith's Council of Fifty Practiced Plural Marriage?

While there may not be a precise list specific to the council of fifty there are books on polygamy that include names like Nauvoo Polygamy (George D. Smith), More Wives Than One: Transformation of the Mormon Marriage System, 1840–1910 (Kathryn M. Daynes), Identifying the Earliest Mormon Polygamists, 1841-44 (Gary James Bergera) which mentions 14 of council of fifty in 1844 (48/74), and Joseph Smith’s Polygamy vol 3 (Brian C. Hales) that I could find.
