In Clayton cemetery there are five DOBLERs. Mother MARGARET DOBLER 1877 - 1942 & Father GOTTLIEB DOBLER 1879 - 1962. They share the same stone.
There are 2 DOBLERs that share the same plot and that's JOHN DOBLER & LOUIS DOBLER, along with Ruben West. Unfortunately they don't bear any dates
There is also a ROYAL DOBLER, and that stone also doesn't bear any dates.
I hope this helps a little. Sorry it couldn't be more helpful.
