I am researching David Turnbull b 1846, he is my wife's great-grandfather. We have some information about him and photos of his grave. We would like to make a connection with anyone who may have information about his family. Went out to photograph his gravestone on Friday, Aug 10, 2012 in Shawnee, Ohio, Shawnee Cemetery. Found some children's and a grandchild's gravestone as well. We have a photo we think is David with his grandson also. We look forward to hearing from anyone who may have information.
