http://wc.rootsweb.com/cgi-bin/igm.cgi?op=SHOW&db=caferg...I prefer not to post my research notes, because I'm writing my Ferguson family book and I will include them in a chapter on this very special family, whom I'm fortunate to be related to. Hopefully, the book will help preserve the memory of my great granduncle and aunt Edward F. and Hannah K. Rath.
In the mean time, I would be happy to accept updates and corrections from living Rath family descendants.
