What is or are the mechanism(s) behind the naming conventions for a church building or organization? What is or are the mechanism(s) behind the naming conventions for a church building or organization in a denomination, say Presbyterianism?

This question can be reworded as "When churches assign names to themselves in this fashion 'First Presbyterian Church; Second Presbyterian Church; Third Presbyterian Church', are they accounting for the fact that there are other Presbyterian churches in the locality (regardless of the sub-denomination or organization name, evangelical or mainline) or that there may be other churches in the EXACT same sub-denomination under Presbyterianism and that one Presbyterian church chooses to name itself as a way to distinguish this Presbyterian church from that Presbyterian church?"
Catholic Parishes are faith communities named after a Catholic Saint; a combination of Saijts whose names appear together in the Liturgy of the Mass; a title of Our Lady;  or a title of the Holy Trinity.

Examples: 


St. Augustine Parish
Sts. Pepetua and Felicity Parish
Holy Mother of Consolation Parish
Divine Mercy Parish
