Yah,
Jackson is super popular. I don't like it much. Every time I hear a person is going to name their kid that, I do a invisible eye roll. Its just has no substance, imo.
Jack is 100 times better. I guess
Jackson came about when everyone was adding -sen and -son to everything.
Jackson Daniel is close to
Jack Daniels and I wouldn't use it, but at least he has a less trendy name like
Daniel to fall back on.
