Helping my Brother David due to his wifes passing

I'd like to help my brother David with the recent passing of his wife Patrina. She unexpectedly passed away on Dec 23, 2023, she was in her early 40s. My brother married into her family bringing his son along with him, and basically adoped hers in the process with 2 of them currently still in school. She was extremely important to all of them and kept them all together, now at this point help is needed with funeral costs and other expenses during this time. Anything helps, even a dollar.
