Daniel was the 2nd of 12 children born to Stephen Buffum and Hannah Sewel (or Weed). Two of Daniel's brothers, William Gilbert & Hiram Barney headed west toward Yamhill Co on the Oregon Trail in 1845 & 47; Hiram died & was buried on the trail in ID. Another brother, Jonathan had a son, Abel Cooper who headed west to CA in 1890, settling with several of his children in Shasta Co.
It appears that Daniel lived in Fulton Co, IL for most of his married life. He enlisted in the War of 1812 w. a NY Cavalry unit & later w. the NY Dragoons.
He applied for bounty land in 1850 & received 40 acres in 1853.
There is a military marker beside his grave which reads: "Daniel Buffum NY Pvt, Capt Ithiel Stone's Co, 1st Regt, 2nd Brig, 3rd Div, Cav, War of 1812 from June 11 1814 to June 14, 1814."
