It doens't seem that all your variables are relevant to the execution of your program - I don't see you using 'orville', 'tiffany', or any of those. Also, you might not need to create a whole struct if you're only going to ever have one of them.
In main() the lines where you say
entrys.orville;
entrys.tiffany;
entrys.robin;
etc,
are unnecessary. While they will compile, they don't affect anything.
But as for your grid, I'm sorry I don't understand what you're goal is.
