Is the name of the place "taco johns"? Can someone please confirm the same and update the map accordingly if yes?

The borders of this element(relation/128584) are incorrect in multiple places. They should be fixed to match the parent administrative element or at least the state borders. If the borders of the parent elements are incorrect then they should be fixed instead.

Our users indicate that this building is "Saint Benedict Catholic Church". We cannot find any available sources to verify this information. Can any local mappers confirm this? #msftopenmaps"
