I know this is because of enemy's curses and negative karma. If I will do a working to empower them, they could go in others directions and fall even more, I know this from experiences with meditations. I am thinking to do a working to break the negative karma for the whole family, but I don't know what to focus on. I don't know how to express this better, but I hope is clear enough.
Don't get in a trap of spending too much energy on other people, but at the same time, they are your family. You can do something small that adds up over time, for example.
Going through their entire karma will be hard to do, or will take a lot of energy. You should prioritize certain goals, based on what is needed most urgently. First focus on their safety and health, for example. Also, you don't necessarily have to start by removing karma if another action would work better. If they fight with you or others, then use ehwaz. If you want to incite them to do something, use Raidho or Kenaz (like take care of their health).
Otherwise, you could simply do RTR's on them, and this will do them a big benefit in regards to keeping enemy curses off them, as well as removing past ones on their souls. You can take a picture of them and set it up on your computer, then do a 3x RTR on an adjacent window. Then briefly clean the whole family. This will do a good service for them, especially over a long period of time, and shouldn't take you that long either.
