Seymour origins

may have been in northern France.  But
their first recorded sightings were in
fact in Monmouthshire on the Welsh borders in the mid-13th century.  Sir William Seymour, who was an attendant to
the Black Prince, was the first to use the anglicized version of the
name.  His son Roger established the family
home at
Wolf Hall in Wiltshire.

Sir John Seymour was the first to bring the family into
national prominence.  He took an active
in suppressing the Cornish Rebellion of 1497 and afterwards attended
Henry VIII
at the Field of the Cloth of Gold.   His
daughter Jane became the King’s third wife; his son Edward, created
Duke of
Somerset, acted as Lord Protector following the death of
the King.

The Seymours were never again
to be so close to royal power again.  In fact
Edward the Lord Protector and his brother Thomas, who had married Henry
widow Catherine Parr, were both executed for treason in the early
1550’s as the
political tide turned

family did remain haughty, influential and wealthy for several
generations after this,
although they split into several lines including a few illegitimate
ones as
well.  The Protector himself was married
twice.  Probably due to the adultery of
his first wife Catherine whom he repudiated in 1535, his titles and
were entailed first on the issue from his second wife Anne:

  • Edward
    Seymour of
    this second marriage became the Earl of Hertford.  His
    descendants re-adopted the title of Duke
    of Somerset until this male line died out in 1750.
  • Edward
    Seymour of the first
    marriage meanwhile established himself at Berry Pomeroy in Devon.  Six successive Edward Seymours followed, the
    last of whom succeeded as Duke of Somerset in 1750.
    From Francis Seymour, a second son, came the
    Marquess of Hertford line.

Marquess of Hertford line had become the most
conspicuous Seymour line by the late 18th century.
Their numbers included Lord Hugh Seymour, a
senior naval officer who was for a time a close drinking friend of the
Regent. He died of yellow fever in the
West Indies in 1801.  His younger brother
George, once described as “the handsomest giant in the world,” was also
carouser with the Prince.  He lived on,
an inveterate place-seeker, until his death in Brighton in 1848.   From this line or thereabouts came the Seymours of Thrumpton Hall

The Seymour name has also been evident in Hampshiire since the
mid-16th century when Sir Henry
a brother of the Lord Protector, acquired Marwell Hall near Winchester.  There had in fact been earlier sightings of
the name in Andover.  One Seymour family
line at Ringwood has been traced back to Robert Seymour who was born in
Lulworth in 1624.

Seymour name extended into Ireland.  One
line via John Seymour, a second son of the Seymours of Berry Pomeroy,
apparently settled in Limerick where James Seymour was recorded as
mayor in
1729.  From this line, it is thought,

  • Sir
    Michael Seymour the naval
    officer who saw combat with the British Navy during the Napoleonic Wars
    and rose
    to be Rear-Admiral.
  • many
    other Seymours in Limerick who at this time were
  • and
    Horatio Nelson Seymour who was
    a prominent merchant in the city from the 1830’s to the 1870’s.  

Francis Seymour of the Hertford
Seymours was in charge of the British troops stationed in Antrim in the
1700’s and his descendants became sizeable landowners in the Lisburn
area.  Another Seymour branch in Ireland
around this time with Thomas Seymour, also an army officer who with his
John established himself at Ballymore castle in Galway.

.  Colonel John Seymour was
appointed the
colonial Governor of Maryland in 1704.
He came in fact from the Bitton Seymours of Gloucestershire, an
illegitimate line from the Lord Protector.
Upon his death in 1709 his family returned to England. 

, a Puritan from
Hertfordshire, came to New England in 1635 and
settled in Norwalk, Connecticut.  His
line through six generations was covered in the 1939 book A
History of the Seymour Family
by George Seymour and Donald
Jacobus.  One line extended to Horatio
Seymour who served twice as Governor of New York and was the Democratic
candidate against Ulysses S. Grant in 1868.

John Granderson Seymour arrived in North Carolina in 1792 from
England.  Family legend has it that he
came as a remittance man in that he had left his influential family
behind and
severed all family ties.  In 1829 he headed
west with his family on horseback to Morgan county, Illinois where they
settled.  Esther Seymour Atwood’s 1960 book
The Descendants of John Granderson and Agnes
covered this history.

York.  There he became a popular Irish

Seymour line and consequently had to fend for himself.
He served as a colonial administrator in
various parts of the world before becoming the Governor of British
Columbia in
1864.  He only lasted in the post for
five years before his death from dysentery.
But his name has lived on in a number of places in the province.

Maurice Seymour was
said to have been born in Ireland around the year 1820.  After
serving in the British army, he migrated from Jamaica to New York and
