Common questions
What twin name goes with Onyx?
Matched same-sex options: Wesley, Rowan, Lincoln, Silas.
For a girl twin: Sophie, Iris, Sarah, Esther. All share Onyx's style and syllable count but start with a different letter.
Should twin names match more than sibling names?
A little. Twins are introduced together for life, so names that sound alike and share a style work well — but names that rhyme (Onyx with a near-rhyme) sound like a comedy act, so they get marked down hard here.
Why do distinct initials matter for a twin of Onyx?
School registers, medical forms and camp lists often go by first initial and surname. A twin of Onyx whose name also starts with "O" gets mixed up with Onyx on paper for years, so the twin score rewards a different first letter.
Where does the data come from?
Onyx's rank and the ranks of the twin names above come from US Social Security Administration records; how well each pairs with Onyx on style, length and sound is scored by NamePairings — see the how-we-score page.
