Swathi: A variant of Swati, which comes from the Indian name of the third brightest star in the night sky, called Arcturus in the western world. This spelling is used indian actress and television presenter Swathi Reddy and is the only spelling that charts in the US.
Suraya: An Arabic name that is a variant transcription of Thurayya. This is the only variation that charts in America however.

Sri: A varian transcription of Shri meaning “diffusing light, radiance, beauty” in Sanskrit. This is another name of the Hindu goddess Lakshmi. In India and other parts of south east Asia, Sri is also used instead of Ms or Mr though for many it brings to mind Sri Lanka.
Simisola: A Yoruba name meaning “rest in wealth”. It is the name of a 1994 crime novel which was turned into a telemovie in 1996.

Shemaiah: A male Hebrew name meaning “heard by YAHWEH” in Hebrew. This name is borne by several characters in the Old Testament including a prophet in the reign of Rehoboam. I don’t normally recommend male names on girls but this one is so rare on boys (doesn’t even chart, and hasn’t since 2002) that it could easily work on a girl.
Sevilla: The Spanish form of the city of Seville and the name of a Spanish football team. The cities name suposedly means lowland though some sites have it as a Spanish form of Sybil. It is pronounced Sev-ee-a
Sevana: Either a rare femine form of Sevan, which means lake, sometimes used in Armenia or other sites list it as a native American name meaning grassland but since none give what language that’s in, chances are it’s not true.
Sahar: Sahar is used by Azeri Turkish, Arabic, Hebrew, and Persian speakers. In Persian, the name means “just before dawn”, referring to a poetic word for the crescent moon. Nameberry lists it as meaning “dawn, morning, awakening”. The Arabic verision Saher was also used five times.

Sayumi: A Japanese name with over a dozen different translations.
Sa has five: 沙 a kind of fabric, 佐 save/rescue, , 小 small, 早 fast ,寿 joyous (event)/ auspicious

Mi also has six: 見 (see), 未 (which I can’t find the meaning of), 美 beautiful, 実 seed/fruit,三 3, 弥 more and more

Sayani: I can’t find much information on this name) most however agreed that the name was of hindu origin but only one offered a meaning: Evening though I don’t know how correct that is. Either way it’s bound to be getting more popular since a famous bearer of the name, Sayani Gupta starred in one of the highest grossing Hindu films “Fan” in 2016 and starred in the critically acclaimed drama “Margarita with a Straw” in 2015.
Saxon: From a German surname meaning knife. It was given to 44 boys last year but since it’s a rare surname with out a gendered meaning, I think it could easily work on a girl as well.
Satsuki: A Japanese firstname and surname, when given as a first name it translates to: 咲月, “blossom”, “moon/month”, 沙月, “sand”, “moon/month”, 幸希, “happiness”, “rare/hope”
Samrawit: An Ethiopian name meaning She Is Unity or She Who Unifies, while I did find other meanings that weren’t Ethiopian, I looked on social media to find people with the name and most lived in Ethiopia which makes me believe that it’s the real meaning.
Salsabeel: A variation of Salsabil (Arabic: سلسبيل Salsabīl) an Islamic Arabic term referring to a spring in paradise (Jannah).It can also mean river or fountain in paradise.The sole Qur’anic reference is in sura Al-Insaan. It is the only spelling that is currently used as a first name in the US.
Saleema: The feminine form of Saleem, which itself is a variant of of Salim, meaning safe. Saleema is more commonly spelt Salima, which was twice as popular with 10 girls given the name. It does seem that both forms are legitimate though Salima is the most common form in the Arab world.
Sajida: An indirect Quranic name for girls that means “one who prostrates”, “one who is a devout worshiper of Allah”.
Saija: A Finnish diminutive of Sari and is pronounced Sie-yah. If you can look passed the spelling and pronunciation issues, it’s a lovely choice.
Saidah: An Arabic name meaning faithful. It’s pronounced as Sah-EE-Dah not Sai-dah like I originally thought.
Safıye: The Turkish variant of Safiyyah, the feminine form of Safi an Arabic name meaning pure. It is pronounced Sah-fee-yeah so most American’s would choose the traditional Arabic pronunciation, especially since it is spelt in Turkish with a dotless ı but the five born in the US would be Sufiye as the ı isn’t allowed in the United States.
Sadira: Another choice from the Middle East, this one from Iran. Sadira is a Persian name meaning Lotus Tree, a variant of the Pakistani Sidra. And I think it’s a great choice that can work on a Western child and appeals to those who like Sadie but are looking for a more unusual full name that was only used as much as Saedi, Sadiee and Sady, while still being a legitiment choice.
Saanvika: A Hindu and Sanskrit name, that is another name for the Goddess Lakshimi. The goddess of weath, fortune and prosperity. It’s a variant of Sanvika which was given 10 times.
The rest of the series, however long it will take will be done using the 2015 data, I won’t be revisiting the end of the alphabet most likely at all.

I know quite a few people named Suraya or Thurayya, and variants of Safiye, and one Sunita (called Nita for short, but I think Sunny would be cute). I think Salima and Saleema are really pretty, although I’ve never seen them on a real person.
I know tons of Saxons of all ages – the first Saxon I ever met was a woman, who was about 20 or so years older than me, and would now be in her late 50s or early 60s. I was quite surprised when I discovered it’s usually a boy’s name, and I’ve never met another female Saxon. I think she might have been born in Britain, but I’m not sure.
I’ve never met a Saxon, but I do think it works better on a boy. I know a Sidonia who’s my age but I don’t know anyone else with any of the names covered
