[@Sigil] Hmmm. I have a slightly hairbrained idea. Or several. 
-The Crypts aren't religious and they're quite odd, maybe the church suspected they were soulless and sent Mary to the manor 
-Virginia perhaps went to the church to ask if they had any way of determining where someone's spirit is (her parents were lost at sea) 
-Virginia has a bit of an oddness to her in general...She's honestly really weird, almost anything could work if you're interested in figuring something out
