My niece and her 6 children are fleeing domestic abuse coming to Houston from TN

My niece is planning to move here from TN. She's escaping her verbally and physically abusive ex. She has 6 children and the last five are 9,8,7,6 &5. Believe me I know how insanely selfish it is to have so many children. While she shares some of the responsibility, domestic abuse had a lot to do with this. Spousal SA and also not being allowed to use birth control. Anyway she is coming here bc she doesn't feel safe anywhere else and hopes that TX is the last place he will look. My question is are there programs to help her get a place to stay find a job and get on her feet? If you know of any can you please list them in the comments. The children will have literally nothing and they'll need to find an affordable place to live so all the money she can scrape together will have to be used to get down here. I dk how she's gonna afford a place beg enough for all of them or any place at all for that matter
