Before I answer, how are you pronouncing it? I say GRAY-um, and find the GRAM prn a bit odd.
1. I really don't know if I like it. It's kind of an old-man name to me, and it's a common surname where I'm from as well. It's not really my cup of tea, but I don't dislike it either. Haha sorry that wasn't very helpful was it!
2.
