I have just posted an Ittel Family Tree which provides information on the Ohio line of Ittels. It is good to see that some of the names match up nicely with what you have mentioned. Barbara Ittel, Hammel, Charles Kronig, and Magdelena Kronig all show up.
Unfortunately, the various Ittel lines do not seem to have been very creative with names, so Philip, George, David and John show up repeatedly in various lines.
