if we are looking for the same person i am on a facebook page that is armenians of sudan i can post a message to see if anyone on there would remember him or his family most of the people that post on the facebook page are 30-70 year olds. someone on there knew my great aunt and my great uncle. i am not sure how popular kassabian surname is but i have only heard it a few times. i am almost positive this karnig i knew of was living in sudan with his parents. when my grandma knew him he would have been in his late teens to early 20s
