@Pudding01 - I don't find any of your choices boring but if you wondered, I count "true" classics as names that are always in the top 100 historically: Alexander, Charles, George, James, Thomas and William.
Fairly classic names to me are those that are very well known and that are often/currently in the top 100, like: Samuel, Michael, Henry, Matthew, David, Daniel, Jacob, Joseph, Frederick, Luke, etc.
Less common classics are imo traditional names not often used now or that have fallen out of favour: John, Hugh, Peter, Phillip, Robert, Christopher, Stephen, Richard, Nicholas, Mark etc
