Jack Tar

 

Jack Tar

John was the most popular name for a boy from around 1150 to 1470 and its pet name or diminutive was Jack, which became widespread from the late fourteenth century onwards. It denoted an ordinary or low-class man, or peasant, and was applied to any low-born or common male.

It gave rise to expressions like, ‘Every man Jack,’ meaning every man in a group, with no exemptions.

 ‘Jack of all trades (master of none)’ indicated a person who could turn his hand to any task, while ‘Jack the lad’ described a youth who was self-assured and maybe roguish. These idioms are still used today.

In the seventeenth century, someone trying to improve his social standing, to ‘rise above his station in life,’ would be described as ‘Jack would be a gentleman.’

There are a few suggestions for how the name Jack Tar came to be applied to sailors. In the seventeenth to nineteenth centuries, when wooden sailing vessels relied on wind for power and propulsion, the rigging for the sails was hemp rope. Being permanently in a damp atmosphere, they were prone to rot, so were covered in tar, which had to be replaced frequently. Tar was also used on the deck planking, and the ship’s hull, to make everything waterproof. Sailors were therefore often liberally coated in tar. Tarpaulins, canvas material coated in tar, were used to cover objects on deck, and sailors’ clothing was made of tarpaulin. It was but a short jump from the name of the material to the name for the man.

There is a belief, unsubstantiated, that sailors tarred their hair, which they wore in a long plait, to prevent it being caught in the rigging. This led to another plausible legend, that the purpose of the square collar of a sailor’s uniform was to protect his uniform being stained by tar from his queue or plait.

Coopers were skilled craftsmen in the nineteenth century whose job was to assemble or maintain casks on board. When a barrel of wine or spirits was emptied, it would be filled with boiling water and rolled about. The drink thus produced was known as grog and the coopers became known as Jolly Jack Tars or groggers.

The invention of grog is ascribed to Admiral Edward ‘Old Grog’ Vernon. His nickname came from his habit of wearing coats of grogram (grosgrain) In 1740, he sought to counteract and reduce inebriation among his crew, by adding water to the rum. With the addition of lime juice, to combat scurvy (and the reason Englishmen are called ‘limeys’) and sugar to sweeten the taste, grog became a staple drink.

Natives of Swansea, in South Wales, are known as Jacks, or ‘Swansea Jacks.’ Swansea men had a reputation for being skilled seamen and, as such, their services were greatly desired by the navy.

  1. Fascinating information! I love when you blog about STUFF of importance -Jack is a favorite name for dogs it seems. I have known many.
    Tarred pig tails sounds mighty disgusting doesn't it? Good luck sailor...

    1. I haven't known any dogs called Jack, but my youngest grandson is Jack, my oldest grandson's middle name is Jack, and a very nice, much older neighbour is called Jack, every man Jack of them! 😉

    1. There's a lot of military and naval parlance in our family and sometimes I feel the need to dig a little deeper.

  3. I've said before, and will say again: I'm so very glad to have found your blog finally. I thought I was a magnet for "useless" information but you certainly have me beat by a country mile.

    1. Yes, indeed, I'm a font of useless knowledge and can stop any conversation short with an odd observation, hence why I am more a listener than a talker! 🤣😂

  4. I remember when I was a kid, a man told me that Jack was the same thing. That was news to me the, and nobody has called me Jack since.

  5. I can only think about tar stained white pillow slips. The ship's laundry boy will have had his work cut out for him.

    1. I don't think laundry was an abiding issue in those days . . .

  6. My only nephew in England (I have three nieces) is called Jack. He got married in October and cut a dashing figure in his formal suit - not a drop of tar on him!

    2. It certainly is! The first time I met him he was a remarkably well-behaved (but not shy) boy of eight or nine.

  7. My grandad was called Jack and also my nephew, although I am sure there were never any sailors in our family.

    1. I think Jack is a lovely name - very reassuring, somehow.

  9. Isn't it interesting that one word can attach itself to loads of other stories. I never knew Jack was a nickname for John. Thelma

    1. John Kennedy was known as Jack - I'd forgotten that.

  10. since many of these are familiar here in USA I followed this one easier. I know that John, Jack, Robert, Charles, William, Edward are all our older seniors names, born in the 30's, 40's, 50's. Our Sunday school class of 15 couple, had 5 Roberts our of 15 men. My husband is Robert and his dad and older brother were both John. I forgot James in the list of names, we had a lot of those in the family and several Charles

    1. My father was Charles Edward, and one of his brothers was William. My son's middle name is William. My husband's father was Charles and his grandfather was Charles, too. One of my grandsons is Charlie and his younger brother is Jack. It's strange how names recur through the generations.

  11. I once knew a fellow named Jack. I worked with him in fact. He was given the name Jack, not John, not Jacques, but Jack. I never noticed any tar in his hair, though.

  12. Interesting background information on a name. I enjoyed the read. I had an uncle Jack who was born in the early 1900's but his given name was not John. I have a Jonathan who we call Jon but spell it without the "h"..

    1. It's interesting to think where and why names were given to family members. Sometimes it''s tradition, of course.

  13. Another interesting read and I do like the images you've found and used too :)

    We have some Jack's in the family and a few with John as middle names!

    Names can be so interesting and why are Henry's often called Harry's?
    Of course you may already have a post about that in draft!

    Happy Sunday and Happy 1st of March.

    All the best Jan

  18. Always interesting reading here. I had heard that Navvies dunked their hair in tar to keep it out of the way and getting caught in things.

    1. It would make sense. We underestimate navvies, I think. Without their sweat and muscle we would not have roads and railways, tunnels and mines, among other things.

  19. Another informative post. One of my cousins served in the U.S. Navy on a submarine during wartime. I just can't even imagine doing that.

  21. My father was a John Charles...called Jack and he was definitely a jack of all trades. There was seemingly nothing he could not do. One son's middle name is John in his memory.

    While you are on terms in royal naval history, there is also the lore of why some sailors came by the name of 'snotties'. I remember my mother telling me about that one. :)

    1. I had quite forgotten about snotties - they were the Midshipmen, lowest officer rank, and lacked handkerchiefs!

  22. Interesting. I'm skeptical about men tarring their hair to keep it out of the rigging, though. Wouldn't they just cut it?

    1. Long hair was a sign of virility. Barbers were in short supply on ships.

  23. How interesting. I would think being covered in tar would be very uncomfortable, but what do I know? I liked a show on HBO titled Gentleman Jack about Anne Lister, an 1830's lesbian in Yorkshire. I was very disappointed when HBO ended it because it was intelligent and the acting was excellent.

    Love,
    Janie

  24. I knew the name Jack was derived from John. However, it is not a name found in our family, past or present. Interesting to read about how the name 'Jack Tar', applied to sailors came about and the other naval connections.

  25. We have both Jack and John in our family.
