I also have searched for information on Ganem and also Ghosen. Elsie Ghosen was my grandmother, though she died when my daddy was about 12. Her parents came here from Beruit, Lebanon. Elsie was born in OR. Her father returned to Beruit and the family always felt he deserted his family. I am an optimist and tend to think that news was not as widespread in the early 1900's and something may have happened to him. Elsie's mother was Alma Ganem who had been married to Anton Ellis Ghosen.
How have you been doing on your research. I have had no luck finding any records for Lebanon.
Thank you for your response
