In regards to whether there were graves on the property; yes. They buried children up to around World War II. The graves were once marked, but the nuns took down the markers in the late forties when they found out they were not following protocol and could have legal problems. I got my information from Sister Philamina(Not sure of the spelling). I was there from 1954 to 1957 and actually saw some of the shallow graves where I worked in removing some small boxes. They were buried south of the small house where Father Senasi lived. I served Mass at his little chapel and talked many times of the buried children. I was chosen for the work, because Father Senasi told them I could be trusted. There was also a grotto just north of where the bodies were buried.
