Seanna Mitchell is a Canadian swimmer, who mostly competes in the freestyle events. She claimed a silver medal (4 × 100 m freestyle) at the 2007 Pan American Games in Rio de Janeiro, Brazil.
I guess you could consider this a feminine version of Sean, so it should be pronounced like "shawna", but I have a co-worker called this and it's pronounced see-anna, so it's a case-by-case basis haha.

Anyone see Anna? Cuz that's what this name looks like lol.
Seanna is also used in Ireland, as a masculine dimitutive form of Sean. An example is Seanna Walsh, an IRA volunteer and Republican prisoner at Long Kesh.
