Mr Hannā Mikā'īl Māmā was born in Zaghartā, al Shamal, Lebanon on 22 June 1893 1 before moving to Tripoli, Lebanon in later years.
He was the son of Max Māmā and he is known to have had several siblings. He lived in Tripoli where he worked as a farm labourer and it has been suggested that he and his family originally hailed from Kfar Hātā, Zaghartā.
He boarded the Titanic in Cherbourg as a third class passenger (ticket number 2677 which cost £7, 4s, 7d) having already made the voyage from Beirut to Marseille. His destination was to the home of his cousin Thomas Betros of 1001 Ellsworth Street, Philadelphia, Pennsylvania. He possibly travelled with Tannūs Butrus-Ka'wī and Sarkīs Lahhūd Ishaq Mu'awwad of Zaghartā, among others from that locale, including the Nakid family.
Māmā survived the sinking, possibly in one of the aft starboard lifeboats (possibly 15). The story that came down through the family was that he had been picked up out of the water by Mrs Astor's boat but there is no evidence to support the claim. He reached New York and was eventually reunited with his family in Philadelphia.
Hanna, who had anglicised his name to John Mami, had been married, possibly around 1918, to a woman named Elizabeth Starr (b. circa 1892) 2 who was born to Lebanese parents, Sarkis and Katherine Starr. The couple had no children and appear on the 1920 and 1930 census records living in Philadelphia. He initially worked as a grocer before operating a public house, Titanic Cafe, until his license was revoked for buying stolen alcohol. He then ran an ice-cream parlour before moving to Washington, DC in the mid-1940s where he operated a Pool room.
Hanna (aka John) died in Washington, DC on 18 April 1952 and he was buried in Fort Lincoln Cemetery, Suitland, Maryland.
