Shannon, moved after the Revolutionary War to
Anderson county in east Tennessee.
- a line from another brother Thomas went to Tennessee,
Arkansas and Texas. Alexander May Shannon led a Confederate
cavalry unit during the Civil War known as Shannon’s scouts. He
later settled in Galveston.
Thomas Shannon, probably from Ulster, settled along the Savannah river
in Georgia in the 1770’s. His son Owen, a member of “the Old
Three Hundred,” came to Texas as early as 1822. The area there
was lawless in those times and his son Jesse was said to have been part

George Shannon was brought to America from Munster around
1760 when about he was about one year old. He knew nothing about
his parentage except that his father was an Irish merchant and that his
mother had died on the crossing with him. He grew up,
fought in the Revolutionary War, married, and later moved to
Ohio. He had three notable sons:
- the eldest son George, nicknamed “Peg-Leg,” was the youngest
the Lewis and Clark expedition that crossed America from East to West
in 1806. George
Shannon later settled in Missouri and Shannon county there
was named after him.
- Thomas was a Ohio state politician who served in the Ohio
House of Representatives.

Governor of the state in 1838 and subsequently Governor of Kansas
Most Shannons generally came later. The peak decade
for immigration was 1850-1860. Patrick and Mary Shannon, for
instance, came to New York around this time. New York recorded
the largest number of Shannons in the 1920 census.
Another Patrick Shannon came to Worcester, Massachusetts in the early
1900’s. His son William became a prominent journalist and
commentator on the political scene who was appointed US Ambassador to

Shannon was Catholic from county Antrim who came to Canada in 1832 and
in Prince Edward county, Ontario. It was

and Catherine Shannon came from Sligo to Ontario
in 1847. Their son William left his home

Shannon was a Cariboo
pioneer and one of the hard-working and hard-playing men from the rough
civilization of the 1860’s. He was a
trader, miner, freighter, and cattle rancher who came to British

married his wife Catherine in Hinton, NSW. One
son Thomas stayed in this area, owning property
in Umarra, another son John moved to Queensland.
Derry arrived as free settlers to South Australia in the late 1830’s. First came Abraham and David Shannon in
1839 and 1840, followed by their father William and his second wife. Abraham moved to Moculta in the 1860’s and his
family mausoleum can still be seen there on the outskirts of the town. David operated
a large farm at Yatara in the Konnunga district.
The Shannons had by their own account been at
Ballycragy in county Antrim for eight generations and more than two
years before they made the decision to emigrate to New Zealand in the
1860’s. The eldest offspring George was
the first to arrive in 1865, followed by three of his brothers. They made their home in the Wanganui area. Their story
was told in a family book published in 2000, A
Shannon Family – from
Antrim to New Zealand.
