Help for my sis & niece's for a unexpected death

My sister and nieces unexpectedly lost their husband and father yesterday. As most may know my sister has been raising my niece Jasinia, since the loss of our other sister a few years back. Times were tough but they made it work. We all know that this is a tough time of year for our family and the holidays are right upon us. I am asking for help as so they can take the time to grieve and process what is going on and not have to worry about all the financial burdens they are now faced with. I also know that my sister is a huge believer in karma and has done for others in need. Now is the time that her and the girls need our help. Anything you can do is appreciated, more than you can ever know. Thank you and please feel free to share
