The story of Brenan
Irish surnames are mostly frozen phrases: a word meaning descendant or son, plus an ancestor's personal name, fixed in place around the eleventh century and carried unchanged since. That structure is why so many of them can be taken apart into ordinary words, and why the meaning that results is usually a description of one long-dead individual rather than of the family. The single or double n in this one is not a matter of taste — the Irish original has one, and the doubled spelling entered through English scribes writing the surname down as they heard it.
Meaningscholars disagree
Descendant of the little drop
The Irish personal name behind the surname joins a word meaning a drop or moisture to a diminutive ending. Whether the drop was meant as rain, a tear, or sorrow is disputed, and several distinct Irish families carried the name independently.

Fashion outlook
Brenan sits outside the current charts, and that is its own kind of answer: naming cycles can only date the names they carried up. A name this rare has no decade stamped on it — it cannot go out of fashion, because it was never in.
