Blu
A unisex name with no widely documented etymology — one syllable, given to 24 babies a year in England and Wales.
Blu by the numbers
In 2025, 24 babies in England and Wales were named Blu. In the US, 24 were, though that figure is from 2017, the most recent full year we hold.
For the size of the two countries, it is given several times more often in England and Wales than in the US.
Its best year in America so far is the most recent one on record, which means it was still climbing when the records end.
What we can tell you about Blu
Not every name has a meaning to trace. Plenty are coined rather than inherited — invented outright, blended from two names, or respelled from an older one — and where we cannot find an etymology we can stand behind, we would rather say so than make one up. What follows comes from the birth records themselves.
