Margaret Ditterline was born in Amsterdam Holland. She migrated with her family before 1810 to Pennsylvania,America. Margaret married John Cook in August 20, 1814. At one time there was a reference to a daughter Rebecca born in Virginia before leaving for Kentucky, but that has not been supported by any other research. They migrated to the extreme southeast corner of Graves County, Kentucky in 1820, just one year after it became a county. The territory was a hunting ground for the Chickasaw Indians. The friendly Indians showed them where water was and good hunting places so they could survive. This area was treeless with a few springs to supply water, therefore it was known as the "Barrens". An area later was known as "Cook Spring, a mile from Boydsville, and it is assumed, without research, that this is the area where John Cook and his wife Margaret Ditterline settled on the state line road of Boydsville Community about 1820, before there were many other white settlers. They put a tent beside their wagon and lived in it for eighteen months. John built a one room log house in the yard. It had a dirt floor and overhead the logs had slabs on top of them to make a floor for the upstairs room where they raised six boys:
William Ditterline Cook (1815-1882)
John Wesley Boyd Cook (1818-188810
James Johnson Cook (1820-1848)
Edward Robinson Cook (1821-1862)
Lewis Benson Cook (1823- )
George Washington Cook (1826-1906

Margaret was living alone during the 1850 Graves County Kentucky census. She gave as her birthplace Pennsylvania. Margaret gave as her acres ownership 1000. This is the land that apparently the oldest son William, was to farm later and he and his family are also buried in the Cook Cemetery. Another one of her sons, John Wesley born 1818, and his family lived next farm down. He acres were 1200. The burial ground on his land became "Boston" Cemetery and holds several of his siblings and family.
