For as long as I've lived (34 years) our Americanized family pronounced our name as 'eye-cone-oh', minus the 'a'. Other Americans have pronounced it the way it's spelled 'eye-ah-cone-oh'. On my last trip to Italy I mentioned our name to a multitude of natives and they all pronounced it as 'ee-ah-cone-oh' with the emphasis on the 'ah'.
'ee-AH-cone-oh'
Are there any other pronounciations to our name hanging out there???
