So you "own" your children? They are your property? They are yours to do with as you like?
Then you can not be a free individual as you are owned by your parents. To say that someone owns someone else is entirely wrong in my opinion. Your children own themselves, no one can claim their ownership. While they can not fully support themselves you, as a parent, are responsible, but that is something entirely different from ownership.
On to wikipedia, they state in their guidelines that their content should reflect the commonly accepted theories EVEN IF THEY ARE PROVEN WRONG!
Go ahead and read them for yourself.
