Saint Totnan (7th Century – July 8, 689 AD) was an Irish Franconian apostle.

Kilian told Gozbert that he was breaking Christian scripture by marrying his brother's widow, Geilana.

Geilana retaliated by sending her soldiers to the main square of Würzburg, where the three were preaching, and having them beheaded.

He transferred the relics of the three men into the new cathedral which was dedicated to St Kilian.

[2] Totnan was posthumously named patron saint of the Bishopric of Würzburg.
