If we are trying to link the excavated bone remains to one of these two historical figures, we can theoretically do this by comparing the main features of the skull with the facial features on the tombstones. While some of the main features of the skull remains may correspond to the features on Abbot Sigfrid's tombstone, the facial features of László Czudar do not have the slightest reflection to them. 

We have no reliable knowledge about the extent to which the tombs were made to faithfully reproduce the personal physical features and facial features of the deceased. Researchers should also be cautious about the discrepancy between the size of the tombstones and the narrow dimensions of the monastic choir, especially if the tombstones are imagined as part of a tomb with an ascending structure, i.e. a tumba, as is likely to be the case with the tomb of Abbot Sigfrid.

The identification of the bones with a specific historical figure thus remains to be established.
