Dear Mary,Thank you so much for all the Waller information that you sent as well as the sources!  Martha Ann Waller would be my great-great grandmother.  How exciting for me that you sent so much information.  It's interesting that the given name of my great-great grandfather, Higdon (Robertson), is also in your family line.  I have quite a bit of information from Fannie Robertson Arnold through the present (Higdon and Martha's daughter). My email address is pjdivjak@san.rr.com. Please have Ed contact me at this email address. Regards, Patricia Divjak
