In your posting of September 02, 2011 you mentioned the children of Samuel III and Bathsheba Griswold Carver. After an approximate thirty year search (my Dad and I) we have discovered that Gardner Carver had three children: Lyman born in 1802 and Alvin and Calvin (twins) born in 1804. We acquired this information from the McLean County Museum of History in Bloomington, Illinois.
