How to cross the river

A Strange Family now already stand on the riparian, all of them want to go opposite riparian. Totally 8 members in this strange family includibg
1. Father
2. Mother
3. Elder Brother
4. Younger Brother
5. Elder Sister
6. Younger Sister
7. Maid
8. Dog


The problem is now only one old vessel which can only carry 2 members each time. Now we break it down to 3 section
Section 1 : Riparian
Section 2 : River
Section 3 : Opposite riparian

Well, why i do said that this is strange family, because of the below reason:
1. The mother will kill the brothers if father not stay at the same section.
2. The father will rape the sisters if mother not stay at the same section
3. The dog will bite the family member if the maid not stay at the same section

And finally, only father, mother and maid know how to control the vessel.

Now, you mission is to ensure all of them are able to reach the opposite riparian safe (without getteing hurt or kill)
