Warnie is an uncommon, yet distinctive given name of Germanic origin. It is derived from the Germanic elements 'war' meaning 'guard' and '-n-', a connecting vowel. The name was popularized by British author C.S. Lewis, who used it as a nickname for his brother, Clive Staples Lewis, in his semi-autobiographical novel 'The Chronicles of Narnia'. While not widely used today, Warnie retains its unique charm and historical significance.
Warnie is not a particularly popular name, with only 141 recorded births over the period from 1916 to 1956. The highest number of births in any single year was 12, occurring in 1916. After that, there were several years with 7 or more births, but most years saw fewer than 7 Warnies being born. The name's popularity appears to have declined over time, with the majority of its occurrences concentrated in the early part of this period.
