Statistics count the spelling “Llewellyn” as recorded by the publisher. When a spelling has several independent origins, the counts are not split between them. Counts measure applications. Gaps are years without a published value, not zeros.
Rates per million are unavailable for this series because no compatible denominator has been imported.
