Still out there Keith (given I'm replying to a 2002 message)?
You've probably progressed well beyond this by now, but I've just seen the 1886 (at Kelso) death cert. of the plumber Robert FAIRBAIRN who was married to Agnes RUTHERFORD.
It shows his parents as Robert FAIRBAIRN (horse dealer) and Ann CURLE, both deceased.
Do you know if Robert was the son of George FAIRBAIRN and Janet MURRAY? I'm looking at this latter family at the moment trying to figure out if that is where the James who married Helen GOODFELLOW belongs.
