My dad's name was Carl Koch (born 1919), born in Northern Saskatchewan. His father's name was also Carl (possibly Karl, nicknamed Charlie) Koch, born (c. 1881) in Greifswald, Vorpommern, Germany.What would be of interest to you is that Charlie's mother's maiden name was Kasdorf.Apparently, the Koch's and Kasdorfs jointly migrated to Amsterdam/Hagaman, NY in 1883(?).
Charlie, being a bit of a free spirit, left home in NY and became a trapper/hunter/prospector in Saskatchewan, MT, WA, ID, etc.He came back to NY to get a wife (he tended to call all women "woman") and took her back to Sask. The marriage unsurprisingly lasted only 3-4 years.Left with my 3 year old dad, Charlie brought him down to the Great Northern R.R. and put him on a train to his younger sister Rose in Amsterdam, NY.Rose Koch Van Denburgh didn't know what to do with him, so she farmed him out to her cousin Fred Kasdorf in Hagaman (I believe).Dad stayed with the Kasdorf's until he was around 16 when he ran away to find his dad in MT.He found him Charlie in a bar in the Cut Bank, MT area (I imagine a scene like the Johnny Cash song, "A Boy Named Sue").Dad became a cowboy in Ferdig, MT until WWII broke out.
What dad said of the Kasdorf family was that Fred was very "old country".At dinner, Fred ate first and when he finished the other had a go at the food.He had a son, Freddie, who also lived in the Hagaman/West Galway area.I vaguely remember meeting Freddie in my youth.
Great aunt Rose kind of kept in touch with all the family members.Unfortunately, she was childless.There was another sister of Charlie's, Anna, who married Duncan Krueger (Uncle Dunk). They lived for many years south of Vails Mills on Ste. Rte 30 a little ways south of the old drive-in theatre.They had one daughter, Florence, who married Pat Stewart of Hagaman.She was a teacher at Hagaman elementary school and also vice-principal (possibly principal).They lived on Northern Boulevard on the edge of town heading for Amsterdam.
Charlie's oldest brother Herman was a weight lifter in the circus and then joined the Merchant Marine.Family legend has it that he was second mate on a freighter in Tokyo Bay on 12/7/41.He died in a Japanese prison camp.
Charlie's youngest sister Jenny died at an early age.
Another sister, Bertha, married a man named Fick and mover to Roslindale, MA.They had two children Bill (older perhaps 1917 birth?)and Eddie (younger).While I met Eddie I don't remember much about him or his boys.Bill (lived in Newton Highlands, MA for many years) married Mabel (family in New Ipswich, NH).They had two children Susan and Billy.Susan was born in 1946; Billy was youger.Susan lives now in Kennebunk, ME.Uncle Bill was a PT boat captain in WWII, a marine in Korea, and later was in the Army Reserve.He worked for many years for New England Bell Telephone as a maintenance supervisor.
Charlie, I believe, had one more brother (Heinrich?).
That's about all I know.I have Aunt Anna's birth certificate in old German script and my granddad's divorce papers that give his birthplace and date.
