England. An
early example of the surname – Stephen Deyman in the 1224 pipe rolls of
Buckinghamshire – matched the old meaning of the word.
By the next century the “d” had appeared, as
in Dymond. This became in time Dimond
and then Diamond.

Devon Dimond
persisted as a
surname in the west country and particularly in Devon; while Diment
cropped up
in Somerset. The family
line of James Dyment, born in Beaford in Devon in 1767, was variously
Dyment, Diment and Diamond

Kent The Diamond
name also occurred in Kent in various places. John Dimonde was
said to have
arrived in Brenchley near Tunbridge Wells from France in the early
1600’s. The name there became Diamond.

. The O’Diamain
family originated in Derry and Antrim along the Lower Bann river
where they
were an erenagh family which acted as
stewards for the church at Kilrea. Neal Diamond was born in
Maghera parish in
1764. A Diamond branch, stone masons who
worked on the stone at Guildhall in Derry, migrated to Ardnaglass in

Sligo in the early 19th century.

Diamonds left for America during the 19th century.
Patrick Diamond, for instance, came to Pennsylvania in the
1760’s and subsequently migrated to North Carolina.

John Diamond was a ropemaker from Devon
who came first to Massachusetts and then settled in Kittery, Maine in
where he built fishing boats. His son
John was tortured to death during an Indian raid in 1692.

Thomas Diamond or Diman (he himself spelt his
name Diamond) was the forebear of the
Dimonds/Dimans of Bristol, Rhode Island.
He came first to
Connecticut, thence to Farmington, and thence to Easthampton on Long
where he died in 1683.

The name was spelt
variously at that time, but then two different spellings took root:

  • the
    first was Dimond. Thomas Dimond and the
    Rev. James Dimond both came to Bristol, Rhode Island around the
    year 1712.
  • the
    second was Diman. Joseph Diman came to
    Bristol in the 1760’s and raised two master mariners, Captains Royal
    Jeremiah Diman.

was both a Dimont
and Diman Governor of Rhode Island in the 1840-50’s.

Another Dimond line began with Thomas Dimond
who died in Fairfield, Connecticut in 1658.
The spelling subsequently varied between Dimond and Dimon. David Dimon of Weston received rough treatment from the British
in 1777. Henry Dimond was a Christian
missionary from Fairfield who set off for Hawaii in 1834 where he lived
for a
further sixty years. Edwin Ormond’s 1891
book The Dimond or Dimon Family of
Fairfield, Connecticut
covered these and other lines.

Diamond is also a
Jewish name in America. Louis Diamond
arrived from Russia in 1904 and, after studying medicine at
Harvard, made his name in pediatrics. He
has been called the father of pediatric hematology.
His son Jared Diamond is a popular science
writer. Other second generation Diamonds
in America have been the composer David Diamond and the
