Other recorded senses
(measured from records)Shelagh is also recorded in one other lexicon, as a different name or as an ordinary word. These are senses of the spelling, not of the name above.
Another Anglicized form of SÍLE (see also SHEILA ). The final consonants in the written form seem to have been added to restore a Gaelic feel to the name, since they occur at the end of many Gaelic words and are silent. However, they do not have any historically justified place in the name. Variant: Sheelagh .
as a word
Ordered by how much of this spelling's record each language holds, so a sense from a language the name is barely used in sits last rather than first.

About this data
measured from records inferred from the name graph machine-generated
These figures come from the data snapshot of and will change as it is rebuilt.
Statistics are aggregated from the Mondonomo name corpus; related names and etymology are inferred from the name graph; pronunciation and any machine-marked transliterations are model-generated. Read how the numbers are made, including their known failure modes, and where the data comes from.
Reference works we consult — surname dictionaries, official name registers, Wikidata and Wiktionary — are named directly, beside the claims they support. The per-country source counts also include datasets of person records: we publish how many there are and their authority tier, but not their names.
