Tiobaid is a masculine name of Irish Gaelic origin, representing the Irish form of Theobald. The original Germanic name Theobald combines elements meaning "people" and "bold," conveying the sense of "bold among the people." In Irish pronunciation, Tiobaid sounds approximately like "CHI-bid" or "CHEE-bid." This name carries strong Celtic heritage and would be recognized primarily in Ireland and among Irish diaspora communities. While uncommon even in Ireland today, it represents a connection to Irish linguistic traditions and heritage. Parents might choose Tiobaid to honor Irish ancestry while selecting a name that stands apart from more common Irish names like Liam or Aidan. The name's distinctive spelling and pronunciation reflect the rich phonetic traditions of the Irish Gaelic language.

Teasagh or Teasag, which can be Anglicized as Jessie, is a Scottish form of Jean, which itself originated as a Scottish feminine form of John. Scotswomen called Jessie are more likely to be properly named Teasagh than Jessica.
