You are making my point for me. Even though the variant of BLAISE is its traditional etymology, you can't rule out that one (or more) of the others wasn't the intention of the parents. BLAISE [stammerer] is almost certainly its origin when it is chosen euphonically, but you must not impose that interpretation, if his parents clearly were naming him [fiery], [forerunner], etc. Does placing "a trail" in parentheses make you more comfortable? Blaze (a trail).That iteration of "blaze" almost always implies "a trail," whether literally or figuratively.
