Some Catholics practice a devotion of giving personal names to their guardian angels. However, the Holy See does not allow this practice and formally discourages it. According to the Directory on Popular Piety and the Liturgy, 216 (under the heading about Devotion to the Holy Angels):
The practice of assigning names to the Holy Angels should be discouraged, except in the cases of Gabriel, Raphael and Michael whose names are contained in Holy Scripture.A special thanks to Father Gary Selin and my friend Jordan Low for finding this citation.
