Joanne,
Greetings! And yes, I remember talking with you a while back. The Ridinegr history Is poke of is in book form and not accessible via the web. If you are from the Illinois bunch, that means we are probably from the same house, Michael Ridinger's line, as most of his sons stayed in Ohio when my great-great-grandfather returned to Pennsylvania.
Drop me a line and we'l chat.
