The name "Logann" seems to be a variation of the more common name "Logan". The spelling could imply a difference in pronunciation, with a longer "a" sound, as in "lah-gan", rather than the shorter "a" sound in "Logan". Phonetically, this would be transcribed as /lɑːɡæn/. It is worth noting that there are many variations in spelling and pronunciation of names, and it is ultimately up to the person who bears the name to decide how they want it to be spelled and pronounced.
