The names themselves
Meaning, roots, sound and the people who carried each
Where each name comes from
Alena
from Helen — a Greek name whose sense was never settled
Alena descends from Helena (and in some families from Magdalena, 'of Magdala', a village on the Sea of Galilee). The Helena line is clear; what Helenē itself meant in early Greek is not. The oldest serious readings link it to helenē, a word for a torch or basket, and to a root for shining or sunlight; neither has won. Greek naming of that era rarely left an explanation behind.
Helenē → Helena → Elena → Alena
How it traveled
Helenē belonged to Greek myth long before it belonged to churches, and Latin turned it into Helena, which the Roman world carried north and east. In the Slavic languages the initial H fell away and the vowels opened: Elena in the south, Alena in Czech and Slovak lands, Alyona in Russian and Belarusian speech, where it began as a familiar form of Yelena and then stood up on its own.
Kennedi
from Irish Ó Cinnéide, built on ceann, "head"
The first element, ceann ("head"), is not in doubt. The second is read two ways: éidigh, "grim" or "ugly", giving "grim-headed", and an older tradition rendering it "helmeted head". Both are serious; neither has pushed the other out.
Cennétig → Ó Cinnéide → Kennedy → Kennedi
How it traveled
The root is the medieval Irish personal name Cennétig, recorded in Munster, which hardened into the family name Ó Cinnéide and then into English as Kennedy. Irish emigration carried it across the Atlantic in the nineteenth century, where — as happened to Ryan, Casey and Riley — the surname loosened and began to be given as a first name.

Out loud, and in short
Alena
uh-LAY-nuh
Two pronunciations circulate in the US and both are correct: uh-LAY-nuh follows English habits, while ah-LEH-nuh is the Czech, Slovak and Russian version, with the stress on a short middle vowel. Families usually pick one and hold to it.
- Lena — The most common short form across languages, and a fully established given name in its own right.
- Allie / Ally — The usual English-language clip, informal, shared with Allison and Alexandra.
- Alenka — The standard affectionate diminutive in Czech, Slovak and Slovene; used at home rather than on documents.
- Lenka — Czech and Slovak diminutive that also stands alone as an official given name there.
- Also Ali, Nena.
Kennedi
KEN-uh-dee
Stress on the first syllable, the middle one very light. The -i ending does not change the sound: it is said exactly like the surname Kennedy.
- Kenni — Informal, and the short form that keeps the parent spelling's final -i.
- Kenna — Informal; also stands on its own as a given name in US records.
- Ken — Very short and informal; more often heard as a man's name in its own right.
- Kenny — Informal and family-level; likewise established as a standalone name, usually masculine.

The trade-offs, name by name
Alena
Strengths
- Spelled phonetically for English readers — six letters, no silent parts, and most people write it correctly on the second try.
- Carries ready-made short forms in real use, from Lena to Allie, so the child has choices without inventing any.
- Recognized across Czech, Slovak, Russian, Belarusian and German-speaking regions, and close enough to Elena and Helena to be understood almost anywhere.
To consider
- The pronunciation genuinely splits — uh-LAY-nuh and ah-LEH-nuh both belong to the name. Expect a lifetime of gentle correcting, or a decision to answer to either.
- It sits in a crowded neighborhood of near-twins: Alaina, Aleena, Alina, Elena, Elaina. Spoken aloud over the phone, it will often need to be spelled out.
- Because Lena and Allie are shared with several other names, the short form on its own will not always point back to Alena.
Kennedi
Strengths
- Needs no pronunciation help — the sound is familiar to essentially every English speaker, even where the spelling is not.
- Carries a documented Irish line back to a medieval personal name, which few modern respellings can claim.
- Several usable short forms, including Kenni and Kenna.
To consider
- Kennedy is the default spelling, so this version will be corrected and re-corrected for life. Worth deciding now whether you are content to spell it out at every appointment.
- The name is inseparable from the American political family for many people, which some parents like and others would rather avoid.
- The -i ending places the name firmly in a recent naming fashion, and it is easing back from its high point — it may read as of its moment rather than timeless.
