Holy Sepulchre is filled with mausoleums. Nearly every one of them, however, have been vandalized. As the bottom photo shows, all the glass has been broken in the brass doors and covered up with plywood.
I could find no reference to the Itnyer family in any of the Omaha books but someone emailed me in 2007 to say that the occupants of the mausoleum are two of the Creighton women, who each married an Ityner and a McGinn. This makes sense since the Creighton family has others buried near this mausoleum. It is sad that the family doesn't ensure that repairs are made to the building.
