Hi Laura. Yes, actually two obituaries.
Moses T WHITEHEAD d 13 Jan 1905 in Liberty Hill, Williamson, TX and, his wife, Margrett WHITEHEAD (BRYANT) d 29 Apr 1901 also in Liberty Hill.
There are several others who are researching this family and many have posted online but none have posted anything about whether they've found any obituaries or not. Even knowing where there isn’t one is helpful.
Thank you for your advice about where to look. Unfortunately, it looks as if there isn’t anyone at the Williamso County Genealogical Society who is volunteering at the Round Rock Library. I’ll have to find another way. These message boards are sometimes very fruitful.
