Master As'ad Tannūs (Assed Alexander Thomas) was born in Hardīn, Lebanon on 8 November 1911.
He was the son of Iskandar Tannūs (b. 1890) and Thamīn Khūrī (b. 1895) who had married in 1910. His father worked selling fruit and vegetables in their home village.
It was decided that the family would emigrate and his father Alexander travelled ahead first, settling in Wilkes-Barre, Pennsylvania where his married brother Bashīr (known in America as Charles) had previously emigrated to and who operated his own dry goods store there. Alexander sent Charles back to Lebanon to fetch his wife and son As'ad and return with them to Wilkes-Barre.
As'ad, his mother and uncle Charles Thomas (Bashīr Tannūs) and several others from their village of Hardīn left for Beirut where they would cross to Marseille and eventually arrive in Cherbourg. The party boarded the Titanic at Cherbourg on 10 April 1912 as third class passengers (Thelma and her son As'ad on joint ticket number 2625 which cost £8, 10s, 4d) and they were headed to 33 Loomis Street in Wilkes-Barre.
On the night of the sinking Thelma and her brother-in-law Charles brought baby As'ad to the upper decks but they got separated in the confusion, Thelma ending up in a lifeboat with Charles still clutching baby As'ad. It is not certain which lifeboat Thelma departed in: some sources would suggest that she left in lifeboat 14 with baby As'ad being passed to a woman (later identified as Edwina Troutt) who then entered boat 16. Other sources have Thelma departing in boat C and baby As'ad in the arms of Miss Troutt in boat D.
Thelma and her son survived the sinking and were reunited aboard Carpathia. Her brother-in-law Charles was lost.
Hospitalised in New York for the effects of shock and exposure Thelma and her son eventually landed in Wilkes-Barre, Pennsylvania and were reunited with As'ad's father Alexander. He settled with his family at 216 Stanton Street in Wilkes-Barre and he gained nine siblings: Sadie (b. 1914), Edward (b. 1916), Sarah (b. 1919), Helen (b. 1921), Joseph (b. 1923), Mae (b. 1925), Peter (b. 1927), Marjorie (b. 1930) and Jean (b. 1932).
As'ad (or Assed/Essid Alexander as he became known in the USA) died from pneumonia in White Haven sanatorium on 12 June 1931 aged just 20. He was buried in St Mary's Cemetery in Wilkes-Barre.
