James Cottrell 1845-1873 MO IA TN

I am searching for James Cottrell b. 1845 d. 1873. He married Sarah Allen Williams in about 1867. Sarah was born in Iowa on March 25, 1845, her family moved to Lewis County Mo for the 1850 census, and then she was living in Bloomfield, Davis County, IA in 1860. I do not know if she and James Cottrell were married in Missouri or Iowa, but their first child, Wenonah Ann, was born in MO in 1869. Their second daughter, Harriet Elizabeth, was born in Tennessee in 1873. And that is the year our old family records list for James' death, but I do not know if he died in Tennessee. When I find Sarah and the girls next is 1880, living in Pilot Grove, Cooper County, MO. I can find no 1870 census for James and Sarah. I do not know any more of James Cottrell's family--his parents nor siblings. Sarah was the daughter of Jeremiah Williams and Susan Crook, both born in Kentucky.

James and Sarah were my great great granparents. If you think this James Cottrell might be someone in your tree, please let me know.
