I was examining a 5466 (1705/1706) Amsterdam Sephardi High Holiday Maḥzor (4” x 6” x 1½”) covering Rosh Hashanah, Yom Kippur, and the daily Selihoth in between, published in Amsterdam by Isaac son of Jacob de Cordova(בדפוס המשובח של הגביר היקר יצחק בן יעקב דיקורדווא יצ״ו). It is signed in Hebrew as: “חזן מרדכי שלום לונדון” and is also signed in English as: “Hazan Salom”.Do you know anything about him?What year was he born?What year did he die?
