Meaning of DEMICHELIS

Someone might don’t know about his surname, at Livejournal we’ve discussed about this and some had a comment that his surname means:

- DE MICHELI, DE MICHELIS from the first name Michele, derived from Hebrew name “Micha’el” = who is as powerful as God. Patronymic surname.

She’s been searched from this: http://www.italyworldclub.com/genealogy/surnames/d.htm

What do you think, ‘who is as powerful as God’? Wow!!! I’ll search for ‘Martin’ later. I hope that its real meaning mightn’t mean ‘swallow’ as you know. :P
