Family history through gravestones

I went to Oak Grove Cemetery in Portsmouth and took some photos of my ancestors' graves:

Ira and Hattie Wilkerson were Carl's grandparents (parents of his mother, Marguerite Wilkerson Kraft). The younger Hattie was Marguerite's older sister, called "Sister," who never married. There is a picture of the family here.

This was Carl's younger brother, who died in a boating accident (the story of how he died is related here).
