Short English phrases to Old English

Hi,

Can anyone help me with following?

I am currently writing a Dutch novel, which is partly situated in England. I want to include some short Old English phrases in the book. I have some trouble using the only translator, mainly because my understanding of the English grammar terms is, well let's say, non existent.

Right now I am just looking yet for a translation of "yours or mine".

Help would be greatly appreciated.

Regards,
Roy
