Mrs brown has been married 5 times. With each husband she had two children: a boy and a girl. Each daughter has one brother (as well as four half-brothers). She now has 10 children. She has no plans to remarry. All good things must come to an end...

I think that Mr Brown has six children 5 daughters and one son although , although Mr Brown's wife could have a fair with someone else and spoil my theory .
