Outside of the county seat in Buffalo, Dallas County is very rural, with many unmapped cemeteries that have been lost due to neglect, the creation of manmade lakes, or construction of a major highway running through the county.
I have a set of the Cemetery Books put together by the Historical Society and will do my best to chase down the exact location for photo requests.
Unfortunately, weather will impact my ability to find locations — I generally avoid deep woods in the summer (ticks & poison ivy!), and a severe winter/ice storm will also keep me inside.
Dallas County Library has good reference sources for obituaries, and I’ll be glad to check those as well. Exact date of death is helpful.
