The family of Sybrand Koopal. Back row: Martin and William. Front: Case, Tren, father Sybrand (Silas) Koopal and Anton. In right corner, mother Anna Koopal.
SYBRAND KOOPAL was born February 4, 1880, to Martin and Tryntje Koopal in Vrouwen Parochie, the Netherlands. He grew up in this area and worked as a farm hand. He met Anna DeBoer from Hylaard, the daughter of
Wybe Kornelis DeBoer and Rigtje (Jacobs) Vellinga, who was born August 5, 1881. Sybrand and Anna married on April 2, 1903. Four children were born while in the Netherlands: Martin, Wybe, Tryntje, Cornelius, and another son, Sjoerd,
was born at Platte, South Dakota. Sybrand served one year in the Holland army before moving his family to South Dakota in 1910 and settled in a small log cabin along Platte Creek in Hamilton Township.
About a year after living in South Dakota Anna died leaving
Sybrand with five children (eight years to one month of age).
After their mother’s death, Cornelius (Case) and Sjoerd
(Anton) were taken by Anna’s sister, Annie and her husband
Rein Talsma, to Matlock, Iowa. Later they were adopted by
Rein and Annie Talsma. Case kept the Koopal name but
Anton changed to Talsma. The boys grew to manhood there
and married girls from that area. Case later moved his family of three boys to Lyle, Minnesota. He and his wife have both
died there. Anton and his wife have one son and two
daughters and still live on their farm near Matlock, Iowa.
Martin (Mert), Wybe (William) and Tryntje (Tren or
Katherine) stayed with several families in the area
southwest of Platte until they grew up. Martin lived his entire
life in the Platte area. William never married and worked
at various jobs and is now retired in Boise, Idaho. Tren
married William Markus a carpenter from the New Holland,
South Dakota area. They lived in Todd County, South
Dakota; California; and Idaho and retired in Nampa, Idaho,
where William died. Tren and William had eight children
(five boys and three girls). Tren later married DeLoss Dunn
and still lives in Nampa.
Sybrand worked for Ben Wynia for a few years before
starting to farm on his own. In 1928 he bought land from Wm.
Jones in Signal Township and lived in a small schoolhouse on
this land the rest of his life. His son-in-law built a large barn
for him and that was the only other building on the farm. It
served as a horse barn, granary, chicken house, shop and
cow barn. I am sure he led a lonely life and loved to
have visitors, fall being the best time as there were always
goose hunters around. Always he had the coffee pot on and
very few hunters ever left without having a cup of coffee.
Sybrand died November 9, following a stroke in August 1954.
MARTIN (MERT) KOOPAL was born in Vrouwen Parochie, the Netherlands, to Sybrand and Anna (DeBoer) Koopal on August 23, 1903. He started school in Holland and at the age of seven came with his parents, and two brothers and one sister to the United States and they settled in a log
cabin along the Platte Creek southwest of Platte.
In 1911 his mother died and he went to stay with the
Martin Wynia family until he froze his feet and a horse
stepped on his toes. With a very sore foot he was sent back
home. After that he stayed at the Albert Hauzer home and
later with the Matt Huggs until he was fifteen years old. He
quit school then, after completing the sixth grade. Martin
went back home to farm with his father until April 12, 1928
when he married Jennie Dykema, daugther of John and
Grace (Hiemstra) Dykema. Martin started farming on the
Beltman Brothers ranch southwest of Platte. In February
1929 their son John was born there and the following year
they moved to a farm in Signal Township near the beginning
of Cedar Creek. A daughter, Anna, was born there in 1932.
In 1933 the Koopal family moved to the Kelly ranch three
miles west. These were the dirty 30’s and making a living
was pretty tough. Martin worked with the WPA building
dikes on the river near Wheeler and building the roads near
home. In 1935 they moved to a farm in Hamilton Township.
and in 1954 they moved northwest of Platte to farm and
to take care of Jennie’s father. Two daughters, Berniece and
Helen, were born to Martin and Anna while living in
Hamilton Township. Martin caught whooping cough when
his children were ill and suffered asthma the rest of his
life. He liked to play ball and was a pretty fair left handed
pitcher until the whooping cough bout. He farmed with his
son from 1954 until 1968 when he sold his share of the farm in
Hamilton Township to his son John.
Martin (Mert) and Jennie Koopal’s children are: John
married Gloria Steckley, daughter of Adolph and Elsie
(Drury) Steckley of Geddes, South Dakota, in 1954 and their
three children are Rhonda, Tim and Sandra. Anna married
Eugene Vanderheiden, son of Emil and Anna (Pekoske)
Vanderheiden, on June 1, 1951 and they have one son Allen.
Berniece married James Wesseling, son of Mr. and Mrs.
Harold Wesseling of New Holland, South DakotaÄn 1954 and
their children are Carmen, Brenda, Lorna, and Mike. Helen
married Harlin Mesman, son of Mr. and Mrs. John Mesman,
in 1960 and their children are Donna, Dale, Darrin and Darla.
John, Anna, and Helen all live in the Platte area and
Berniece lives at Chamberlain.
Martin (Mert) died March 25, 1970 with complications of
asthma, emphysema and a heart condition.
JOHN SYBRAND KOOPAL was born to Martin and
Jennie (Dykema) Koopal on February 25, 1929,
on the ranch now owned by C. F. Wynia. John grew up on the farm he now
owns. Money was scarce in the early years of his life and he
remembers running barefoot during the summer and then
starting school with new shoes in the fall. It was fun to run in
the fine silt that blew into the fence rows but he almost
burned his feet in the hot dirt. After eight years of school in
the schoolhouse on the corner, John went to work helping his
Dad and neighbors when they needed help. In 1951 he joined
the United States Marines and served as a mechanic in Japan
and Korea. After returning home he farmed the home place,
living on this farm since 1935. John married Gloria Steckley,
daughter of Adolph and Elsie (Drury) Steckley, in 1954 and they have raised their family on this farm.

Sandra is currently attending South Dakota State University at Brookings, South Dakota. John and Gloria irrigated their farm in 1970 and pinoeered the high lift irrigation in South Dakota. They had the highest lift in South Dakota for first year. After that many irrigation systems have lifts even higher. John and Gloria have both been active in 4.H while their children were 4.H and since. Gloria recalls some of her school days going to school in Jackson No. 3 west of Geddes. Her first teacher, Mrs. Emily Meade Riley stayed in the schoolhouse with her dog. Airplanes were few those days but when one new over, Mrs. Riley’s dog let them know and all would go Outside and look at the plane. The skunks bumped their heads when they ran around under the schoolhouse floor. Some days the school did not smell so good either. Gloria went her last year at country school with just her brother and sister and then finished in Geddes.
