Ludwig's remains were interred in the crypt of the Michaelskirche in Munich. His heart, however, does not lie with the rest of his body. Bavarian tradition called for the heart of the king to be placed in a silver urn and sent to the Gnadenkapelle (Chapel of Mercy) in Altötting, where it was placed beside those of his father and grandfather.
I need to look up and study Wägner. In particular his daughter's name who married Franz Liszt. Cosmina? My memory fails me, darn it!
