Unexpected Passing, Leaving Behind Children

My uncle, Dan, passed away unexpectedly yesterday.  He left behind several children that lived with him and relied on him. The youngest is 16.  Their mother lives in another state and is not part of their lives. 
These kids, my cousins, now have nobody, nothing. My dad is doing everything he can and is working to figure out where to go from here. 

These kids have already been through so much, as one of their sisters passed away unexpectedly at at school at age 10 about 15 years ago as well. 

Anything you can donate to help will be passed on to my dad, who will either use the funds for the funeral expenses or to help the kids with anything they need as my family navigates this challenging time of uncertainty.
