Jenna
Jenna is a modern coinage, originally a variant of Jenny (itself from Jennifer). Jennifer comes from the Welsh "Gwenhwyfar," meaning "white wave" or "fair phantom." Jenna emerged as a standalone name in the late 20th century, distinct from Jennifer. The name has no deep historical roots — it is essentially a 1970s-80s creation. Jenna entered the US top 1000 in 1972 and peaked at #45 in 2001. The peak was driven partly by the broader popularity of Jennifer and partly by Jenna Bush Hager (born 1981), the daughter of George W. Bush. Jenna Fischer (born 1974), the actress who played Pam on "The Office" (2005-2013), gave the name a contemporary charge. I find Jenna has a friendly, slightly modern quality — the "J" opening is firm, and the "enna" ending gives it warmth. The name has been outside the US top 200 since 2014. But it has a friendly sound that may cycle back when 1990s naming fashions return. Jenna is a female name of Welsh / English origin that means "White wave (modern coinage from Jennifer)". Friendly, modern, and approachable. The name sounds warm. Jennas tend to be sociable. US peaked #45 in 2001. Outside top 200 since 2014.
