Gary, Yep that's him. William Henry Vallette (b: April 16, 1847, d: Dec 5, 1900). Married to Hannah Newbrey McKinnis.They had three children - Joseph Preston, Edward Franklin,and Iona Ellen.William and Hannah are both buried in the Stockton, Kansas Cemetery
Joseph was married to Gertrude White, she is our tie in to the family.
There is an excellent book "Lest We Forget" published by the Rooks County Kansas Historical Society in 1980 and reprinted in 1998 that has quite a bit of information covering William, Hannah and their kids.
I'll be happy to pass on whatever information we have that you want/need.
