Take no notice of Italian man with son vanishing (6)

I believe the answer is:
ignore
'take no notice of' is the definition.
(to take no notice of something is to ignore it)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ignore that I've seen before include "Discount" , "Walk away from" , "Intentionally disregard" , "Cut head off" , "Fail to notice (6)" .)
