Are there readings exclusive used only for people name? When reading songyuanyao's answer on Are people names always pronounced the same in Mandarin?, I suddenly wonder if Chinese has something similar to nanori in Japanese.

Basically, nanori is a special reading for a Japanese Kanji used in a name. Examples according to Wikipedia:


  
  希 usually has the pronunciation ki (or sometimes ke or mare). However, as a female name it can be pronounced Nozomi.
  飯田 (Iida) uses the special nanori reading of 飯 (ii) and a standard kun'yomi reading of 田 (da)
  


Now, taking the first example from songyuanyao's answer, for Hanzi 費, Wiktionary stated,


  
  fèi with 6 meanings + 2 historical placenames + surname
  bì with 1 historical placename + surname
  


Taking from this example, I concluded that it's used as a surname since it's preceded by a place name.

So I wonder, are there readings exclusive for a name without any preceding usage (meaningless/not used in historical names)?

I think it is very unlikely to have a reading in a name with no meaning at all.

Take a look at the character 樂

The pinyin of 樂 in 快樂 (happy) is /le4/ ; in 音樂 (music) and surname, is /yue4/ 

Which mean when reading 樂 in a surname, it is different from the 樂 in 快樂, but is the same as the 樂 in 音樂.

As a surname 樂 also has a second pinyin /yao4/. (It means 'to love; be fond of; to delight in') 樂進 /yao4  jin4/ is an example.

Although the /yao4/ pinyin can only be seen in classical text nowadays. For example:'仁者樂山，智者樂水', we can't say 樂/yao4/ in 樂進 has no preceding usage.
