Tony, these are the closest in the Maughold marriages to what you wrote:
19 Mar 1881
Robert Birtis KERMENN, Full age, Bachelor, Miner, Maughold [father] John Kermeen, Labourer, and
Annie CORLETT or BARRON, Widow, Maughold, [father] Thomas Barron, Farmer.
No other entries with father Thomas Barron/Barran or Bannan. [IGI has bapt for an ANN BARRON 29 OCT 1843 Kirk German, Father: THOS BARRON, Mother: CATHE LOONEY] If from a different parish the Maughold vicar might have been confused when writing variations of her name?
Other marriages:
May 1856

Mira BANNAN, Full age, Spinster, Maughold, [father] Robert Bannan, Shoemaker.
