To me, Zion, Marley or Zion Marley are "sacred" names for people of Jamaican / Caribbean / Black / Rasta origins or descent that I associate strongly with the anti-colonial struggles of Black people. I don't know any people who have thoseEnames for any other reason. Logan on the other hand is to me a trendy name from the white western culture - totally different and it clashes with Marley completely. I don't know your background or your beliefs, and your name is your decision, but if I met someone in real life who picked Zion or Marley just because they sounded nice or they "like Bob Marley", I'd roll my eyes on the inside.
