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.

Later in the 1600’s John Diamond was a yeoman
farmer and gunfounder in Hawkhurst, a profession also taken up by his
Robert. Jack Diamond (sometimes Dymer)

He was arrested in 1747 but escaped execution.

. 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.

name Diamond) was the forebear of the

variously at that time, but then two different spellings took root:

    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.

who died in Fairfield, Connecticut in 1658.

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
