I heard this name on a little girl at the park, they called her Gensie. It may well be spelled Jensia. Her brother was Robert.
What do you think?
Plus the worst thing that could happen to a name nerd, my son tells me "I don't like Killian I wanna be Joe". This is to my horror but understandable. At the playground Killian tells everyone his name is something like Harry, Dan, Joe or Caillou.. All characters he loves
