Yes, Yoda gives me great powers to find answers (which I don't know myself)...

I was naturally curious when you asked these questions, and so I had to do some research.
I gather if your last name is York, it would mean you are from the city of York (at least back in the day)... Not necessarily making you a dog. Yorkshire Terriers were named after the county of Yorkshire in England, where the breeder is believed to have originated.

Verstegan derives its name from Eure-ric or Eouer-ric, of Euere, a wild boar, and ryc, a refuge; a retreat from the wild boars which were in the forest of Gautries.

Yorkshire Terrier history:
Breed History
HOW THE BREED WAS FORMED
Today's Yorkshire Terrier is very different from the early Yorkshire
Terriers of the North of England. There are varying accounts of the
origins of this breed and its development. I have tried to give the
most accurate, and most widely agreed upon history of the Yorkshire
Terrier assembled from books and publications written be reliable and
experienced fanciers of the breed in the UK.
Before 1750, most British people worked in agriculture. The onset of
the Industrial Revolution brought great changes to family life. In
Yorkshire, small communities grew up around coal mines, textile mills
and factories. People were drawn to these areas to seek work from as
far away as Scotland. They brought with them a breed known as the
Clydesdale Terrier, or Paisley Terrier. These were primarily working
dogs, much larger than today's Yorkies, and were used for catching
rats and other small mammals.
These terriers were inevitably crossed with other types of terrier,
probably the English Black and Tan Toy Terrier, and the Skye Terrier;
it is also thought that at some stage the Maltese Terrier was crossed
with these breeds to help produce long coats. As the outline of the
Maltese resembles that of many of today's Yorkies, this is very
likely. Unfortunately, no records in the form of Pedigrees exist to
confirm these crosses (possibly because of the poor level of literacy
in these times), but a great deal is known about the type of people
who bred them, and there can be no doubt that early breeders had a
very clear idea of the type of dogs they were attempting to produce.
We can see in today's Yorkies how strongly the terrier temperament has
been retained.
Early Yorkshire Terriers and Breeders
One of the most famous early Yorkies was Huddersfield Ben, bred by a
Mr. Eastwood and owned by Mr. M.A. Foster. Huddersfield Ben was born
in 1865 and died in 1871, and can be said to be the father of the
modern Yorkie. In his day "Ben" was a very popular stud dog who won
many prizes in the show ring, and had tremendous influence in setting
breed type.
In 1874 the first Yorkies were registered in the British Kennel Club
stud book. They were referred to as "Broken Haired Scottish Terriers"
or "Yorkshire Terriers", until 1886, when the Kennel Club recognised
the Yorkshire Terrier as an individual breed. The first Yorkshire
Terrier breed club was formed in 1898. During these early years, one
who greatly influenced the breed was Lady Edith Wyndham-Dawson. Lady
Edith was secretary of the Yorkshire Terrier Club for some time and
did much early work for the improvement of the breed. Later, a Miss
Palmer, who was Lady Edith's kennel maid, started her own Yorkie
kennel under the "Winpal" prefix. When Lady Edith returned to Ireland
at the start of World War I, Miss Palmer went to work for Mrs.
Crookshank of the famous Johnstounburn prefix, a name with a long list
of champions, which is now in the care of Daphne Hillman, who was
entrusted with this prefix, and still uses it along with her own
Yorkfold prefix.
Many others have worked very hard since these early years to improve
this breed, and to these breeders much is owed. Many of their early
dogs became the foundation stock of kennels in North America and
elsewhere.
