Jim Eggert, Thank you for the references. I will try to get my hands on those books. My Lindenmeier/Lindenmayer's came from there. I looked to see if any of their spouses were Schropps but none are. Good Luck in your serach. Fred Clarke fclarke@juno.com 10885 W 69th Ave Arvada CO 80004 303 424 2560 ________________________________________________________________ GET INTERNET ACCESS FROM JUNO!
