I am a descendant of Daniel "Duff" Flowers. He was born in either 1836 or 1845. He married Margrett Flowers in 1874. They had about ten children, including my grandfather, Alex Flowers.
I have been able to find them on the 1900, 1910 (and Margrett on the 1920) U.S. Census. But I cannot find them on the 1870 and 1880 U.S. Census.
Whatever help you can give me will be greatly appreciated. There are a lot of their descendants on Facebook.
