I don't think you have the right Armstrong there. This lady spells her name "Katharine" and would much more likely be a commissioner than some lowly staff member.
Surprisingly (to me), when I went to find something to show you the family's background, it seems Tobin, Anne's husband, Katharine's father, just died about 3 weeks ago. Here's the obit that explains some about the family:

Thanks for the info. You're right, Katherine would not likely be a staffer for Whittington. The Catheine Armstrong staffer in charge of cemetery & crematory licensing for the Texas Funeral Service Commission may be a daughter or niece of the wounded-in-the-tall-grass Whittington. Seems just too coincidental to be completely unrelated...
