Emma was kidnapped and almost got sold..

Hayate no Gotoku
Hayate's parent sell him to "nice people" and stuff happens later. If you don't mind that hayate is a boy rather than a girl most of the time lol.

Some guy lurking, but not doing it very well

Actually, try out this list: Sudden Servitude.

I don't know "family selling their child to slavery" - but I do manga that is related to the topic of slavery.

Ore to Akuma no Blues
Historie
Bradherley no Basha
Mother Sarah
Blaster Knuckle
Knights
Vinland Saga

But to be honest, those type of mangas are rare.
I have only seen stuff about slavery when dealing with a historical genre, vampire/supernatural genre, and ...seen as a maid or servant. Really rare to see harsh slavery among manga unless you take into hentai and its ways of dealing with slaves in perverted sexual assaults. Also, robotic slavery - really wouldn't count I guess? I forgot some titles.

Hey, guys tanks, I like rare types of manga the most XD this type is a delicacy to me

Mademoiselle Butterfly instead of a slave she was sold to a Geisha brothel.
