Grandparents graves

We were in Michigan and able to stop by the family plot, and put stones on my grandparents graves. So sad though that they didn't know Jesus. Both my grandparents (on my dad's side) are buried there as well as other relatives:

Maier Gittlen (grandpa)
Betty Golden Gittlen (grandma)
Harry Gittlen (great grandpa)
Esther Schmerin Gittlen (great grandma)
Irvin Feig (great-uncle)
Leon Gittlen (great-uncle)
Ruth Gittlen (great-aunt)
Joshua Gittlen (my dad's cousin)
