I would like to know what ahn in "Maggie: A Girl of the Streets" by Stephen Crane means. It can be read from this link: https://english.hku.hk/courses/engl1039/Crane.pdf
Here are some lines with it:
"Ah, go ahn," replied the other argumentatively.
The little girl cried out: "Ah, Tommie, come ahn. Dere's Jimmie and fader. Don't be apullin' me back."
"Come out in deh hall, Mary Murphy, damn yeh, if yehs want a row. Come ahn, yeh overgrown terrier, come ahn."
