My mom named me Jennica in 1971. She said she made it up...she saw babies named Jessica & Jennifer & she put them together & gave me my name. In school teachers thought it was a typo & called me Jen or Jen. However, all of my adult life I've gone by Jennica & it suits me. The name spelled with 1 n apparently means God is Gracious & there is a young female named Jennica in the bible. My mom did good!
