I just read your 2004 post on the Ancestry.com message boards (
http://boards.ancestry.com/surnames.kmetz/9.3/mb.ashx). It's been several years, so I hope this message can find you. It looks like your grandmother's brother, Andrew Kmetz Jr., married my grandfather's sister, Susan Helen Sanko.
I have also sent you an email. I'd be interested in hearing more about the Kmetz family.
