$100/mo to replenish your emergency fund, $600/mo to debt repayment. Your emergency fund is supposed to cover YOUR emergencies. It's your oxygen mask, so do like they tell you on the plane, "Put on your own oxygen mask first, then assist others with their masks."
In two years, you'll have a $2,400 emergency fund and be debt free. At that point, maybe do something like this...
$70 Poor Relations Fund
$200 emergency fund ($2,400 is probably low. Aim for 6 months worth of expenses.)
$430 house down payment
It sounds like your whole family has hair on fire. When you help them out, you're just trying to keep all of you burning at the same rate. That doesn't make sense. Take care of the only fire you can control: your own.
