Odom-Lawrence Godwin-Lovell-Webb

I,m Looking for any information on my family. They are from Tennessee,Around Columbia. I can't find anything out about my great- great- grandfather- Gray P. Webb. I have been told many interesting stories by my grandmother Mary Webb-Godwin-Lawrence-Stubbs before she died.I would like to be able to do this for my children and grandchildren as well as my brother and sister.There is also a tie to the Gutheries in there and I have a picture of a place in Scotland , a castle GUTHERIE CASTLE
Thank you Linda Lawrence Odom
