Help Ashley McKinney and her 2 sons

Hello, my name is Elijah McKinney. I'm the youngest brother of Ashley McKinney. On September 27 my sister had a brain aneurysm which lead to a massive stroke. She had severe bleeding on her brain and has went through a couple different procedures so far. Currently she is on life support basically fighting for her life. She has 2 boys and was all also pregnant. We got the news on Sunday that she lost the baby. Her 2 boys are now being supported by my step dad and mom. My step dad works 2 jobs and is their only source of income. It's hard enough for him to support themselves now they have 2 more boys to support. I'm not the type to ask for handouts but at this point I'm unsure on what to do to help her and her boys. Anything helps and I appreciate everything In advance.
