Jeff, I noticed from your posts that you are very interested in the Keene family lines from North Carolina that go into Cass County Michigan.
I have been doing quite alot of work on this family and also a few other associated families through marriage into the Keene family.
As you are searching for some information I might suggest that you check out the Michigan State Message Board at Genealogy. com
I have posted several messages regarding Keene family, also Hayden, Lincoln and Shaffer families. You may find these messages helpful and of much interest in you own research.
I am related though not to directly. My Great Grandfather's sister had a daugther named Beulah Taylor who married Clyde Keene. Clyde Keene was the son of Jacob Ira Keene and 1st wife Lydia Ann Graham. Jacob's 2nd wife was Mattie Hayden Keene.
While researching Clyde I became curious about the Keene's which lead me straight to Cass County. Then I started to check out thier background, which lead me to check out the Hayden's, Lincoln's and Shaffer families.
Also check out the website at Find A Grave.com I just this week added several Keene family memorials as well as Hayden and Shaffer and Lincoln's as well.
