Convention for counting dual names

[Richley Crapo]

In classical Aztec, when a person had two names (e.g., Tlotzin Pochotl) and a text refers to the fact that one of these names is the earlier and the other was received later (e.g., "X, who was first called Y), is the person's earlier name listed first or second? In other words, in a case such as Tlotzin Pochotl, would the text likely say "Tlotzen who was first called Pochotl" or "Pochotl, who was first called Tlotzin"?
