I am seeking grave info/photos for Isaiah Dedrick Lawson (guarding Santa Anna fame) said to be buried in White Rock Cemetery (Red River). DRT markers were supposedly set at one time in 1980's. He was born abt 1810. Death possibly 1860. Wife Mary Elizabeth McCowen. His daughter married son of Stiles (also guarding Santa Fame). May be with other family markers with names Stiles & McCowen. Thanks in advance!
