Looked up your Jacoby in the transcription of the Green Valley Cemetery and found the following: JACOBYGustave L.July 3, 1925-Dec 25, 1974
JACOBYFather FRED1871-1933Mother LOLGA1878-1960
JACOBEMother EMELIE6-61886July 20, 1931`
I also have some connection with the Jacoby family of Green Valley, my Grandfather's sister Elizabeth married Fred Jacoby in 1925.
I do have pictures of some of the Jacoby headstones and there are some errors on the transcriptions.The following is from the pictures that I took a couple of years ago.

I thought that I would have taken pictures or the other stones, but it appears that I didn't.I may have done my own transcription, however that information isn't available right now.I live in Texas, but am planning on taking a trip up to Green Valley and even looking in the church records were the cemetery is.If you don't get any further help before then and I do go, I would be glad to look thought the cemetery again. Hope that I helped alittle
