I checked the Posey County Cemetery Records book by Carroll O, Cox.
William and Martha- if I have the right ones, are buried in Mt. Pleasant Cemetery in Smith Twp.
Young, Albert Wm., Sr. Feb 19, 1810 - Jun 2, 1891 Young, Martha A., wife, died May 24, 1864 aged 39yrs, 11mos, 22 days.
On either side of them are more Youngs - a John Sr who died in 1872 (I can give you the exact dates if you need them), his wife Elizabeth and son John, and John's wife, Nancy.On the other side is another John (CW vet), wife Mary, and children Martha, Ada Alice, Cyrena Jane, Lavina, Mary Ann.
Nancy Daugherty, Joseph and Anna are not listed in the index, nor do they appear near Nancy's parents in Mt. Pleasant.A Nancy Curtis does appear, born 1854, died 1940,She seems to be buried by herself in Bellefountaine Cemetery in Black Twp.
