avoir d'un à faire

[Mohawk]

Hello,

I came across this phrase in a play by Feydeau, which, I guess, means I've got something to do.

I was wondering about the construction, which seems a bit weird to me. I just wanted to make sure I'm not missing anything, is this an old way of saying j'ai quelque chose à faire?

Hi,
It's hard to find the meaning of the expression without the whole context. Could you post the complete sentence and a bit of context (things pronouns may refer to, type of dialogue...) so that it could be clearer?

Sure, I'm sorry for not providing it straight away.

It's part of a dialogue and basically someone turns down an invitation for dinner, and the host asks why she can't stay. She answers "Parce que j'ai d'un à faire."
