Origins of -ちゃん


I'm wondering if anyone can provide the origins of the honorific "-ちゃん". It's
a diminutive, and German has "-chen" as a diminutive suffix. Is that a
coincidence?

What is the first recorded use of "-ちゃん"?




Yes, it's most likely a coincidence. We can see this by comparing several
titles:

[code]

    　さま　　ちゃま
    　さん　　ちゃん
    
[/code]

The formal さま, which is clearly Japanese, was shortened to さん, which is now
the most common and general title, and is more or less unmarked. さん was
further reduced to the hypocoristic ちゃん, which is also very common, though not
quite as much; and there is also a variant ちゃま reduced from さま in similar
fashion at a later date, which is the least common of the four.

The earliest cite for ちゃん in 精選版 日本国語大辞典 is 1813, and for ちゃま it is 1900-01.
Although both are after Japan had first been exposed to German, I think the
large majority of borrowings from the German language were from the Meiji era
and later (1868-), following [the opening of the international borders in
1853](http://en.wikipedia.org/wiki/Sakoku). To me it seems like the simplest
explanation is that given by dictionaries, that ちゃん is derived from さん, and is
not related to German _chen_.
