One last thing - there actually were two Daniel Cooks who born the same year and interestingly, ended up in Ontario, Canada. One Daniel Cook came from Scotland and died in 1820. His wife was named Elizabeth. Our Daniel Cook was born in New York State and died around 1858 - 1860. Both Daniel Cooks ended up in Ontario but Daniel (Scotland) died and left a will in Ontario. I could not find a will for our Daniel Cook, which leads credence to my idea that he died in the United States. I did find a history of Grant County Illinois written in 1909 and it mentions our Daniel Cook, coming to Wisconsin right before the Civil War. [the book was about Samuel Cook, son of James Cook, who was the youngest son of our Daniel Cook]
It made researching the Daniel Cook family somewhat of a challenge - not only is Cook a common name, so is Daniel.
