Over a dozen parishes around the country (and probably many more internationally) saw a name change when Bl. Teresa of Kolkatta (i.e., Calcutta) was canonized (i.e., added to the canon — that is, list — of saints) as St. Teresa of Kolkatta. Most still use the archaic form of spelling her city’s name.
Here are the town in which they are located:
Mahanoy City, PA
The cathedral in Pristina, Kosovo
The Dum Dum Cantonment in Kolkatta (I’m guessing that’s pronounced “Dume Dume”)
I’ve only been to the one in Limerick, PA, but it is well worth the visit.
