There are lots of Clark graves at Kawana...a few are unmarked. They have a decoration day up there in July (it's around July 4th.) If you were going to find anyone that knew anything that woud be a good day to go. Have you found a Clark cemetary in Atico near Collettsville? I haven't found that one but I think that's where Harvey Clark is buried. Harvey's children married several Braswells. Myra Braswell married Dolphus and his sister marrieda Braswell too.
