Hi-
I have some more info for the James Buckhannan Greathouse line.
I'm the great-granddaughter of Willie Greathouse (all my relatives know him as Willie Smith Greathouse), born 5 April 1890. Looks like you don't have any info about this line of the family after that generation.
I just registered and so I"m waiting to be approved to tell you more about my family!
