Reilly

What does Reilly mean?

Behind Reilly lies the meaning “The valiant one”. The name comes from Irish — a group of names that has grown noticeably more popular in Germany since the 1990s. Name meanings are rarely definitive; where several readings circulate we list the most common first. Treat them as origin stories rather than definitions.

Sound, length and pronunciation

It is pronounced REI-li. The consonant ending gives the name definition. If your surname also starts hard, the say-it-out-loud test is worth doing.

At 6 letters and 2 syllables, Reilly sits exactly in the range name researchers describe as well balanced — long enough to stand on its own, short enough for everyday use.

How popular is the name?

Reilly does not appear near the top of current German name statistics. For parents looking for a name that appears only once in a classroom, that is precisely the point.

Does Reilly suit your surname?

Before committing: write Reilly out with the surname and read it aloud. Repeated sounds at the join tend to slur together.

Sibling names that go with it

Parents who go on to have a second child often want names that work together. Reilly pairs well with Finn, Liam, Kilian, Ronan, Declan.

Registry offices in Germany, Austria and Switzerland

In Germany the registry office decides whether a first name may be entered. It must be recognisable as a first name and must not harm the child's wellbeing. Austria applies comparable criteria, and in Switzerland the civil registry decides. Reilly is rarer but meets the usual criteria. If in doubt, a phone call to the registry office settles it.
