Meridith,
At least some of these people lived in the 1900's. The Clarks are my parents; my Mother, Louise Allen Clark lived 1904-1985 and grew up in the Shiloh area of Montgomery Co. The Allens are her family members. I remember her talking about Chamber es and Sykes, but I think they were friends rather than relatives. I know our lines coincide somewhere because several years ago I got information about my family from your Family Tree on Ancestry.com or Genealogy.com.
