Where it comes from

The story of Cylas

Silas travels with Paul in Acts and is jailed with him at Philippi, where they sing until an earthquake opens the cell. Silvanus was a Roman god of woodland and boundaries. Cylas is a modern American respelling and appears in the registers in current use.

Meaningscholars disagree

of the forest

Through Silas, generally a contraction of the Latin Silvanus, from silva, 'wood'. Acts identifies Silas with Silvanus, which supports the route. A second derivation from the Aramaic form of Saul is proposed. The forest reading is the commoner.

Spellings of Cylas

#2183
Cylas on the 2025 chart
#60
counting every spelling

The SSA counts spellings, not names. Cylas went to 65 boys in 2025, but Silas and Sylas are the same name said out loud. Together the 3 spellings went to 5,421, which makes it the 60th most-given boys’ name of the year — 2,123 places above the chart.

About 1 boy in 315 born in 2025 was given one of these spellings — against 1 in 26,278 for Cylas itself.

Spellings are grouped by a fixed rule that folds interchangeable English spellings of one sound (ck/k, ph/f, x/ks, a non-initial y for i) and keeps vowels apart, so Sean and Shawn stay separate names. It errs towards splitting: a family here is never larger than the truth. SSA national data, 2025. Method

The Buckley test

Every popular name lives one long story — a climb, a peak, a slow settling back. Cylas's later chapters haven't been written yet, so we borrowed them: Buckley climbed just as high around 1962, and its whole arc is on record. Line the two peaks up, and Buckley's path sketches the road Cylas is walking now.
