Don, Found nothing on "William" but did note this in the Handbook of Texas Online located at http://www.tsha.utexas.edu/handbook/online/index.new.htmlhttp://www.tsha.utexas.edu/handbook/online/index.new.html "36. (0.225) Handbook of Texas Online: SMITHER, HARRIET WINGFIELD SMITHER, HARRIET WINGFIELD (1879-1955).

You can get the longer version by going to the article in the online handbook and clicking on the title.
You might also enter the name of the fort and see if William shows up.
