I’ve lived in NZ for the past 3 years and have worked in a school and as a workplace health and safety educator (at different workplaces each day which means I would get to know the names of between 50-150 people per week) and have never heard Jemaine…although I’ve heard plenty of other crackers!
Out of curiousity I did some research and found this:
Meaning: The French name Jemaine means - a form of [name]Germain[/name] whic I believe means sprout or bud.
**Also, from interview with Jemaine…
SG: What happened to the R in your name?
JC: When my mom had me, she was 17 and it was in the mid ”70s at the height of [name]Jackson[/name] 5 fever. I think she may have even been to a [name]Jackson[/name] 5 concert sometime before she knew she was pregnant with me. So I was kind of named after [name]Jermaine[/name] [name]Jackson[/name] and my parents didn”t want me to be called Jerm in school, so they took the R out. In New Zealand you don”t really say your Rs.
