Our story of Colbi
Ours, offered as ours. Norse settlers in England named their farms after themselves, so hundreds of English villages are one Viking's name plus a word for a settlement — Colby is Koli's, Grimsby is Grimr's, Ormsby is Ormr's. Each is a man who arrived, cleared ground and was remembered for eleven hundred years by a village that has no idea who he was. Koli was called that because he was dark.
Meaning
Koli's settlement
From Old Norse Koli, a personal name from kol, coal, used of dark coloring, and byr, a farm or settlement. Several English villages carry the name and it became a surname.

- counting every spelling
The SSA counts spellings, not names. Colbi went to 29 girls in 2025, but Colby, Kolbi and Kolby are the same name said out loud. Together the 4 spellings went to 173, which makes it the 787th most-given girls’ name of the year — 3,874 places above the chart.
About 1 girl in 9,291 born in 2025 was given one of these spellings — against 1 in 55,423 for Colbi 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
