My great great great grandfather, David W Emery was buried at the Ottumwa cemetery in Ottumwa, Wapello county, Iowa. Unfortunately a marker was not placed at his grave site, but here is a photo of the plot.
Here is the cemeteries record of the burials for the Emery family members at plot 537-M.
David was buried in grave 4 at the top of the diagram. Below is a photo of the Emery & Peck plot. Of the 6 burials, only 3 had markers, Georgia (Emery) Peck, Willie L Emery and Fred J Emery.
