Origin of the Patterson Surname

Exerpt from Surnames of Scotland by George Black Paterson, Patterson

Scottish forms of "Patrick's son" or "Patrickson,
and one of the commonest of Scottish surnames. 
The native home of the Clan Pheadirean(Paterson's)
was on the north side of Lochfyne where they 
were formerly numerous (Carmicheal, Carmina
Gadelica, II, pg.332). See under Macpatrick. 
Patterdale in Westmoreland was formerly 
Patrickdale, "the dale or valley of Patrick." 
William Patrison and John Patonson, 
'gentillmen,' witnesses in Aberdeen, 1446(REA., I, 
pg. 245). Donald Patyrson was admitted burgess
of Aberdeen, 1494(NSCM., 1, p. 37). Ade Patersoun
is mentioned in 1499 (RAA., II, 398), and in  1524
letters were issued against Patrick Patersoune 
for defrauding the king's custom(Irvan, I, pg. 35).
Robert Patersoun was capitane of ane wereschip
of Dundee." 1544(CRA., pg. 205). And John 
Patersoune held land in Glasgow, 1533 
(Protocols, I). Fyndlay Patersoun had a tack of 
the lands of Owar Elrik from the Abbey of Cupar, 
1557 (Cupar-Angus, II pg. 170-171). And in the 
same year John Patersoun custumar of Cupar, 
and David Petirsoun rendered to Exchequer the 
accounts of that burgh (ER., XIX, pg. 80). John 
Patersoune was burgess of Northberwyk, 1562
(CMN., 85). George Patersoun, a monk in the
monastery of Culross, 1569 (Laing, 844), and 
Alexander Patersone, burgess of Aberdeen, 1594
(CRA., pg. 104). William Paterson (1658-1719)
was author  of the ill-fated DArien Scheme and
originator of the plan of the bank of England. 
Patirsone, 1497. Ade Patrisoun had a precept 
of remission in 1536 ( RSS., II, 2033). James 
Patirsone, sheriff-depute of Innernes, 1530, may
be James Patirsoun, provost there, 1573 (OPS.,
II, p. 666-669). One of the Farguharson
genealogies says that "the Patersons in the North"
are descended from Patrick, grandson of 
Ferquhard from whom the clan Farquharson 
take their name (Farguharsons of Invercauld, pg. 4)

Patrick Surname
Patrick, G. Patruig, Ir. Padraig, O. Ir. Patricc, from
Latin Patricius, 'a patrician.' The early Latin life 
of the saint also gives Cothraige, the name by which 
S. Patrick was known during the term of his slavery in
Ireland, but this is simply a  Gaelicized form of 
Pathruig (with c for Latino-British p). S. Patrick's 
full name was probably Patricius magonus Sucatus. 
Tirechan, the saint's earliest biographer, assigns him 
a fourth name, Cothirthiacus, which, however, is simply
a Latinization of the Cothraige already mentioned. Other 
early forms of this name, Qatrige and Quadriga,
suggested to Tirechan and others a derivation from 
quattuor, Latin for 'four:' "Cothirthiacus quia seruiuit
uii[iu] domibus magorum "(i.e. "because he was a slave 
in the house of the four magicians"); "many were they
whom he served, Cothraige (servant) of a fourfold
household" (so the O. Ir. hymn Genair Patricc). The
Tripartite Life(pg. 17) states that he received the 
name Magonus from S. Germanus, and that of Patricius
from Pope Celestine, but this is merely monkish 
tradition. The late Sir John Rhys believed the name 
Magonus to be a derivation from Goidelic magus (whence
Irish mug, servant), meaning perhaps originally a 'boy,'
but is as likely to be the Roman cognomen Magonus. 
Muirchu, author of the first formal biography of the 
saint, says he was also named Sochet (the Sucatus above
mentioned): "Patricius qui et Sochet uocabator." The 
hymn "Genair Patraicc," attributed to S. Fiacc, says:
"Sucat his name it was said," and the Tripartite Life
adds this was "his name from his parents" (loc. cit.).
A note on the hymn, quoted in the last named work
explains this name as "Deus belli uel Fortis belli."
The name is etymologically the same as obsolete Welsh
hygad, 'warlike.'
  In modern Scottish Gaelic the name Patrick is found in
four forms: (1)Patruig, with t and c unaspirated, but
reduced to the corresponding mediae. (2)Paruig for 
Pathruig, in which the t has been aspirated and 
consequently lost and c made into medial g. (3)Para, a
pet or curtailed form of the last. (4)Padair or Patair, 
the common form of Patrick in Arran and Kintyre. This
last form enters into combination with cill, a church, 
in Cill-Phadair, the Gaelic name of Kilpatrick. The
name has thus become confused in popular use with Peter
and is so Englished. (Per contra, Ceann+phadruig is the 
Gaelic of Peterhead in Duncan Macintyre's Oran na gasaid
(Songs, ed. Calder, pg. 392)> "Pedair as a personal 
Gaelic name is hardly, if at all known out of print"
(Celt. Rev., II, pg. 35).In Scotland not only is Patrick
frequently called by the endearing diminutive Peter, 
but Peter is often called Patrick. In fact, it has been
said, Patrick is the "Sunday name," Peter the everyday 
one. In the discussion in the House of Lords on the 
breadalbane peerage claims(1867) the counsel alluding 
to a person who had been mentioned in the course of 
evidence called him Captain Patrick Campbell. The
Chancellor said the captain's name was not Patrick but 
Peter. His Lordship was assured they were convertible
terms. Lord Robertson(1794-1855), who was christened
Patrick, was invariably called Peter(nicknamed "Peter
o' the Painch" by Sir Walter Scott because of his 
rotundity: Maidment Pasquils, pg. 222-223); and Patrick
Fraser Tytler, the historian, was known to his immediate
relatives as "Peter" (Burgon, Life, pg.16). Patrick
was one of the most popular names in the west of 
Scotland in pre-Reformation times, and in Ireland only
became a popular forename after 1600, due probably 
to its introduction by the Scots settlers in Ulster. 
As a surname it is common in Ayrshire, and the old
family of that name appear to have been connected with 
Kilwinning Abbey. Patrick, subprior of Durham, became 
the abbot if Dunfermline, 1201(Annals, pg. 333). 
Patricks of Dunminning, county Antrim, are of Scottish
extraction, descendants of the Ayrshire family. John 
Patric was a notary in 1429(Robertson, Ayr Fam., II, 
pg. 267). James Patrick, heir of Hew Patrick of 
Thornedyke his father, 1658(Retours, Ayr, 501). Robert
William Cochran-Patrick(1842-1897), a distinguished
numismatist, was under-secretary for Scotland. Comes
(earl) Patric was a charter witness, c. 1211(Kelso, 
403). With gille- it gives the common Gaelic personal
name Gillepatrick, hence Macphatrick, and Paterson.
