I too am looking for ancestry on the Khoury family (later changed to Corey) I found something that may be helpful to you on the message board. There is a lady named Debra Corra that is also searching for info on the same family that you are. It is listed on the same message board you have yours on. I believe 2 or 3 pages beyond where yours is. You may have already seen this, but if not I hope that it is helpful to you.
Best of luck.
