Thomas Ismay was born on 7 January 1837, in a small cottage in the town of Maryport, Cumberland. Some time after Thomas's birth, his father Joseph Ismay started a timber business, shipbrokers and shipbuilder. He bought shares in five vessels coming in and out of Maryport. When Thomas was six the Ismays moved to a much larger house in Grasslot, Maryport. The entire family moved to the dwelling because of the 3 sisters Thomas's mother had. The home's name was "The Ropery", the name deriving from the ropes being used at the ship yard laid out in front of the home. This house was near his grandfathers ship yard. This was the first place where he was employed. He spent much of his time around the harbor. He learned here about the sea and navigation along with his most notable habit, of chewing tobacco, giving him the nickname "Baccy Ismay". When Thomas was 12 he was sent to High School in Brampton, Cumberland. This school was one of the best in all of Northern England.
