To Whom Shall I write to first?

Or is it who? Just because I am an English major does not mean that I am always confident that I am properly using the correct form of who vs. whom. In fact I am extremely self-conscious about attempting any sort of grammar whatsoever. It really is quite the conundrum. I insist on taking a grammar class before I graduate, just so I can be somewhat confident. For once in my life I would like to put a comma in a sentence, a semicolon in the next, knowing that it is completely logical.
Anyway...
I have gone about my room and have written down  a few names of people whose writing I have enjoyed. These are not all the authors that currently reside in my room, but they are the ones that have made the most impact in my life. Some are no longer with us, but that will not stop me from writing to them

This list will most definitely get longer with time. This is not everyone that I have read, but it's a start. The order has nothing to do with my opinions of the authors, this is merely the order that I found them in my room. Now, will the authors actually read my Thank You notes? I have no idea, almost all of them just have the address of their agent listed, so I guess it really depends on the agent.
There is also the questionable Louise Riley who I cannot find any information about. The book that I read by her was Train for Tiger Lily, which is a kid's book that was given to my mom. I remember I read it after I took a train to New Mexico to visit some cousins of mine and I loved it (I was 8).
My approach for these Thank You notes is to first address the Authors that are still living. Then  I will move on to honor the deceased bards of human emotion. I still don't know which one to write to first, so that will remain a mystery until tomorrow.
