No1 There was a Cronan aboard:
The documentary evidence from the National Archives at Kew:
I have found that on one side of the family 11 of my ancestors were in the merchant navy, a subject on which The National Archives records are very comprehensive. The other side of my family came over from Ireland in the 1850's at the time of the potato famine.
My great grandfather William Cronan worked for the White Star Line ocean liner the Olympic in the 1920's. He rose up to become a chief electrical greaser, however conduct records show he was demoted for starting a fire on board. He was on the ship the Britannic when it was sunk in the Aegean in 1916. Luckily he survived along with nearly all the crew and passengers.
Less fortunate was my other great grandfather, who by chance also worked for the White Star Line and was working on the Titanic when it sank. It seems he made it off the ship but sadly froze to death in the water. For many years his wife was misinformed that her husband's body had been lost at sea, in fact he was buried in Halifax, Nova Scotia. By way of compensation for the loss of her husband her daughter received piano lessons from the Titanic fund.
