I have taken a quick look through my notes and can't find any record of a Campbell Haddow - most of the family that I am tracing are from the area around Kilwinning and Loudon in Ayrshire. Is that where your family is from?? What do you have on Campbell Haddow - do you know when he was born or where??
Do you have my email address?? If not, please contact me that way and I will share what I have with you on the Haddow family as well as my rather distant connections to it.
