Open Question: Can you send a Western Union anonymously?

A friend of my family is going through a very tough time, and needs to come up with a large amount of money fairly quickly. I would like to send $500 to her, but I would really like to send it autonomously. I thought about FedEx-ing cash, but it could get lost. Someone mentioned Western Union. I have never used it before, but on their site it says I can go to a location and send money overnight. Will they let you do it anonymously? Also, do they deliver the cash / check to her door? Thanks.
