How to add the source/author at the end of the quote?

I’ve been searching this for hours and hours.

Codex says about Quote in post formats:

Suggested Styling
If you were to put the quote into the post content alone, and put the quoted person’s name into the title of the post, then you could style the post so as to display the_content() by itself but restyled into a blockquote format, and use the_title() to display the quoted person’s name as the byline. (http://codex.wordpress.org/Post_Formats)

So how to do this in a custom theme?

The problem:
In content-quote.php I moved the_title() right after the_content(). In the single post view the title drops after DIVs which the different plugins put there, i.e. WP About Author and Ad Injection. Of course the title (or the source or the author of the quote) should be before any of them.
