Unless the name is known I go with the same idea that for mutants/non-mutants: Use the one relevant at the time.

For example, an alternate appearing at some point will have the name of his prime version at that time (Erik Lensherr and not Max Eisenhardt for Age of X for example). And by extension, if an alternate reality is clearly the alternate version of another alternate reality (Some Age of Apocalypse being a variant of Earth-295, it follow it, or Monarchy of M for House of M).
