Barnard was a 9th generation Champlin in America. He had a very complex Champlin ancestry. His father, Hugh Lafayette Champlin was a member of the so-called "Blind Family" in which 5 of 10 children were born blind.
I think Hester (Ruth Hester) was Barnard's daughter by way of his 1st wife, Vada Rowlett. I say this because Vada died in 1910 and Hester was born in 1907. Shortly before Vada's death Vada and Hester were enumerated together as mother and daughter in the 1910 Census.
I do not have a wedding date for Barnard and 2nd wife Matilda but am guessing it was a couple of years after Vada's death as their children together were born in 1914, 1918 and 1921.
