Erica is a typically masculine name that means “forever ruler” or “always ruler.” It’s an Old Norse name derived from the Norse word “Eirikr” which means “sole ruler” or “ever powerful”. While the name Eric can be traced to Norse origins, several cultures and traditions also lay claim to the name.
In Ancient Germanic, it was one of the most common names for boys. Across Denmark, Norway, and Sweden several kings and members of royalty have been given the name Eric. One of the earliest bearers of the original form of the name was Eirikir inn Rauda who was also known as Eric the Red. He was a 10th-century explorer who discovered Greenland.

 However, feminine variations like Erica and Erika are typically preferred for girls. Eric is also a short form of the name Frederick. Eirikir is made up of two elements, “ei” which means "always or ever," and “rikr” which means "ruler."

Although Eric has been a historically popular name in many regions of Europe, it hasn’t always been a popular name in regions like America and England. In the 19th century, it experienced a surge in popularity. This can partly be attributed to the popularity of the children’s novel “Eric, or Little by Little” written in 1858 by Frederic William Farrar.

According to 2020 data from the Social Security Administration, Eric is the 198th most common name for boys in the United States.1 Eric enjoyed the most popularity in the United States from the mid-sixties to the late eighties. In those years it stayed consistently on the top 25 list of most popular names for boys. The peak of its popularity was in 1970. In that year, 23,574 babies were named Eric. Eric is no longer as popular as it was a couple of decades ago, but it remains a solid choice for a baby name.
