Hi Peggy I don't know of any Perry Hollow in Madison County but there is a Perryville and a Perryville Falls (a gorgeous natural falls) and a Perryville Cemetery. This area is just a couple miles or so from Chittenango NY and I was a the Cemetery a couple times. It could be that the area between the village and falls could have been referred to as a Hollow but I never heard of it being called that. Regards Pat R.
