According to a German newspaper, Pope Benedict's father met his wife through the 1920s' equivalent of craigslist. I can't really stand in judgment, since my paternal grandmother's parents met in much the same way.
Bild am Sonntag said 43-year-old Joseph Ratzinger senior placed an advertisement as a "low-level civil servant" seeking "a good Catholic girl, who can cook and sew a bit ... to marry as soon as possible, preferably with a picture," in a Bavarian paper in March 1920.
The second advert in the Altoetting weekly Liebfrauenbote stressed the gendarme Ratzinger's "irreproachable past" and said that while it would be "desirable" if his bride had some money, it was "not a condition" for marriage. [Link]
