From Smithville take hwy 153 North from hwy 71 past Buscher State Park. At intersection of hwy 153 and 2104 stay to the left to stay on 2104. It appears that most if not all of the people listed buried at Powell Cemetery near Smithville are actually buried at Saint Mary's Cemetery. I know this because I have relatives buried at Saint Mary's and you have listed as being at Powell Cemetery. If you look on Find A Grave website and look at the listing for Saint Mary's Catholic Cemetery at Pin Oak you will find a correct listing for Saint Mary's
