The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Boston
Botolph's stone
The English town of Boston takes its name from a boundary or market stone associated with St Botolph, a seventh-century Anglo-Saxon monk. Botolph itself comes from Old English Botwulf, generally read as "messenger wolf" or "herald wolf".
Botwulf → Botolph → Bōtolphes stān → Boston
How it traveled
The name starts as a place: Boston in Lincolnshire, on the tidal river Witham, whose name is understood as the stone of Botolph, a seventh-century Anglo-Saxon monk who founded a monastery in the area. In 1630, English Puritans — many from that part of Lincolnshire — named their new settlement on Massachusetts Bay after it.
Kylian
Most often read as "church" or "little church one"
The underlying Irish name Cillian is usually traced to cill, "church" or "monastic cell", with a diminutive ending — roughly "little one of the church". A competing reading connects it to ceallach, an old Irish word taken as "strife" or "contention". Scholars have not agreed, and both readings are seriously held.
Cillian → Chilianus → Kilian → Killian → Kylian
How it traveled
The root name is Irish: Cillian, borne by a seventh-century monk who left Ireland for Franconia and became the patron saint of Würzburg, where his feast is still kept. Through Latin the name settled into German as Kilian and into Czech as Kilián, staying alive on the continent long after it had thinned out at home.

Out loud, and in short
Boston
BOSS-tun
Stress on the first syllable, which sounds exactly like the word "boss". No r anywhere in it, so the pronunciation holds up in most accents; some speakers say the ending closer to BOSS-tin.
- Bo — The most common short form, and a well-established given name in its own right for boys in the US.
- Bos — Informal, mostly spoken among family and friends rather than written.
- Bossy — A playground or sibling nickname; worth knowing about in advance given its other meaning.
Kylian
KEE-lee-ahn (French) or KIL-ee-un (English)
French speakers say KEE-lee-ahn, sometimes compressed to kee-LYAHN. In English-speaking countries the Irish-derived KIL-ee-un is common, and the y in this spelling also pulls some readers toward KY-lee-un. Whichever you choose, expect to state it.
- Ky — The most natural short form in English, informal, and used as a standalone given name by some families.
- Kyli — Informal, mostly household use; close enough to Kylie that it tends to stay inside the family.
- Lian — Takes the back half instead of the front; also a given name in its own right in several languages.

The trade-offs, name by name
Boston
Strengths
- Everyone can already spell it and say it correctly on the first try — a rare thing for a name this uncommon among children.
- Comes with a short form, Bo, that works as a standalone name and needs no explanation.
- The documented line runs back to a seventh-century English monk and a stone in Lincolnshire, so there is real history under a modern-sounding name.
To consider
- It names one particular city, and people will assume a connection — family roots, a college, a team. If there is no link, expect to answer the question often, and cheerfully.
- The city's sports teams are famous enough that the name may pick up jokes or loyalties that have nothing to do with the child, especially outside New England.
- Its use as a first name is very recent, so it currently reads as belonging to children and young adults rather than to any older generation. That may or may not matter to you.
Kylian
Strengths
- Backed by a documented line running from seventh-century Ireland through German, Czech and French use — an old name in a modern spelling.
- Recognizable across several European languages, so relatives and travel documents abroad rarely find it strange.
- Short, obvious nickname in Ky, with the full form still easy to say for a child learning to write it.
To consider
- It has at least two live pronunciations — the French KEE-lee-ahn and the English KIL-ee-un — and no default in American classrooms. Deciding which one is yours before the birth certificate saves years of gentle correction.
- Kilian, Killian and Cillian all exist alongside this spelling, so the y will need repeating at doctor's offices and on school lists.
- In American ears the opening syllable sits close to Kylie, and some people will hear or write it that way at first.
