Research to find heirs and people

I have a list of people who are now deceased and I need to find their heirs. I need someone who is familiar with ways of doing legal research, contacting courts, and doing other things to figure out a way to find out who the heirs are. Most likely this will require some probate research. I need to get a name, address, and phone number for the rightful heirs of these people. I have attached a sample of 10 people that I need the research done for.
