My husband's family are from Marrakech - family name TANGI, his father was a rabbi in Marrakech and then in Paris, Rabbi Shlomo Chaim Tangi z"l. Name can be traced back to Spain.
Just to add in case its of interest that Rabbi Tangi, wrote a book on shchitah which has been published and can be made available to anyone interested. He also performed many brit milot in Marrakech between 1948 and 1971 and he recorded all the details. My husband is looking into publishing this in book form to allow people to search for details for geneological purposes. He established a synagogue - Etz Chaim - in Paris. Died 15 Av 2003 and is buried on the Mount of Olives.
