Hello, I found the inscription "App. alla con m. ss. immacolata" on a great-relative's gravestone. The stone is worn so it is possible that I made out some of the letters incorrectly but I was hoping that someone would be able to give me an idea of what this means. It is obviously something religious about going with something immaculate but I do not know what app. m. and ss. would be abbreviations for. Thank you.
