Common questions
What are good middle names for Theodore?
For Theodore, the list opens with Alexander, Asher, Owen, Arthur, Emmett. They were picked for how they sound after Theodore, not for popularity alone, so a less common name can sit above a Top 10 one.
Is a one-syllable middle name good with Theodore?

Middle names of three or more syllables (Alexander) make it sound fuller and a little more formal. Match it to your last name: a short last name goes with a longer middle name, and the other way around.
What initials should you avoid with Theodore?
Check the initials on paper before you commit: first, middle and last letters together should not spell a word you would not want on a bag or a towel. None of the 24 middle names on this page start with "T" like Theodore does, because a repeated first letter costs points here.
What is this list based on?
Popularity figures for Theodore and for each suggested middle name come from US Social Security Administration records. The pairing score is our own, worked out from length, sound, first letter and style — the how-we-score page explains it.
