How to list an unfinished PhD on a resume
Don't worry, this is a very understandable situation.  You should just be honest about it.

I don't think the fact that you started a PhD but were unable to finish it due to financial and family circumstances will be counted against you in a professional context, especially if you otherwise have a record of successful employment. 

It would be more of an issue for pursuing a further career in academia (either another PhD or academic employment), since the PhD would be highly relevant to the work you wanted to do, and you might not have any other equivalent experience on your CV.  But outside academia, I don't think it matters much at all, particularly since you have been employed since then.
