Probably from Shelta munik, name, possibly alteration of Irish Gaelic ainm, from Old Irish; see nŏ̄-men- in Indo-European roots.(American Heritage® Dictionary of the English Language, Fourth Edition)
First attested 1849, of Unknown origin. Amongst suggestion are back-slang for eke-name, the Shelta word munik, or monk. Partridge (A Dictionary of Historical Slang) suggests it is a corruption of Monogram which fits well with the use in the sense of signature. (Wiktionary)
