I finally know it! :D
in reply to a message by I like old names
I was browsing a website that listed saints' feast days. I decided to see if some of my family and relatives were named after a saint on their birthday, so I decided to see if my grandaunt, born January 7, was named after a particular saint. When I saw the saints whose feast days are January 7, I saw one St. Nicetas of Remesiana. Knowing that other names with the same elements such as Anecita and Mercedita come from Aniceta and Merceditas respectively, I knew that Necita was a feminine variant of Nicetas!
