Is your name "related" to your problematic letters/syllables?

Is your name "related" to your problematic letters/syllables? Everyone has their different letters/syllables that create problems or blocks. Some people stutter on vowels, so a-e-i-o-u, I stutter on letters like d-t-k-c-s-f-p-b (not even a single vowel) (but still like a third of all letters fffuuuuq). From what I noticed, one of the most shared/common issue that we stutter on our names. My first name starts with a k/c sound, which is in my list of (highly) problematic letters. All my names don't start with vowels and I don't stutter on vowels. Does anyone else experience this? Are your problematic letters/syllables "related" to your name (like vowels, etc.)?
