Above is a copy of the cemetery plot map of the I.O.O.F. cemetery in Alexandria, Madison County, Indiana for John W. and Ellen (KING) WRIGHT. They are buried in Section C, plot 242.
I visited the Monroe Township Trustee's office today, and they were generous enough to provide me with a copy of the plot.
The trustee added the directional arrows and placed the question mark on grave number 1. Ella WRIGHT is buried in grave # 2, and John W. WRIGHT is in grave # 3. Grave # 1 appears that it is much smaller, and that it could be for a child.
Ellen [Ella in the record] was buried in 1913, and John in 1945. John was listed as having a vault, but not Ellen. I went back out to the cemetery to double check that there were only two stones.
There are only two stones, one for Ellen, the other for John, with a larger stone that says "WRIGHT" on both sides. The plot is located just inside the cemetery near the war memorial monument, and is along the edge of the circle drive.
While this is not conclusive proof, it does lend some credence to the fact that an infant or two might be buried with them in this cemetery plot.
