Luc Holtz is a former Luxembourgian football player. He was the manager of the Luxembourg national under-21 football team. He is currently the manager of the Luxembourg national football team, succeeding Guy Hellers.
The name Luc was relatively common during the first few decades of the 20th century, and became very popular during the 1960's. It's popularity decreased after the 70's but it is still used quite often.
I don't like this name. It looks kind of incomplete and I don't like that the only vowel is the French U. Besides, it's completely overused in French textbooks.
All of the provided pronunciations aren't entirely correct. It is difficult to explain the French pronunciation to English-speaking people. The 'u' in Luc sounds like a mix between a short "ee" sound and a short "oo" (as in 'look').
