I just started looking into my family history and saw this thread at the ancenstry.com site. There are certainly a lot of Ottenbreit in Grayson that's for sure. I grew up a short distance from there and many of my cousins, aunts, uncles live there as did my grandparents. Anyway, Anton Ottenbreit & Gertrude Zimmer (from Moladi, Bukowina, Austria) it seems were my great grandparents. I have a fairly detailed set of papers that pick up at the point when then immigrated to Canada on April 28, 1900.
Anway, not sure if anyone is still interested, but I thought you may want to share some information.
