From the late Alberta Lisk:
The plat of Chester Township shows three unidentified cemeteries. All were probably small private burying grounds. One is located in Section 29 and has only one stone located on a farm some distance from any road. The inscription reads:
Charlie E. died June 1, 1862 aged 3 yr 6 mo
Horace Jan. 6, 1857 aged 8 mo 1 da
Sons of M. and E. Hinrichsen
Another is shown just south of Lincoln along the Primm Road in Section 7. Nothing remains.
Another was located in Section 3 near the Chester-East Lincoln Township boundary line.
From Jean and Norman Pyle:
Some stones from the Downey Cemetery were moved to the Atlanta Cemetery around 1880.
Paul Adams says there was a Clear Creek Cemetery in Oran Township on private land. No stones remain.
