Thanks very much for your input guys. much apprieciated
i have come across the book which refers to his son and I have found the names of sir andrews balfours sons being baptised in edinburgh(oddly enough he had 3 sons all called andrew, could this be due to infant death?) but as i said, most biographies say he died without issue. Im offshore at the moment and i think the fire wall is stopping me from completing payment on scotlands people, i may need to wait until i get back onshore.
the comment about andrew balfour of north bank is very interesting as well, Ill see if i can find the source which mentions him.
the sir micheal balfour of denmylne 1759, is the GGson of alexander balfour 3rd Bart of denmilne, not the son of sir andrew balfour(alex and andrew were brothers)
I have already done a great deal of work on this family and am in the process of uploading the familly trees i have done to my website, denmylne.co.uk see the history tab. Im doing this as part of a grant application to historic scotland for work to be done on denmylne castle, which i recently purchased. the other balfour trees will be uploaded to the site as soon as i get back onshore, i have competed 8 balfour trees so far. It is strange that it is relativly easy to trace back as far as 1200 ad but making a link between 1700 and 1800 is so difficult, it must have been a time of great movement and upheaval. I really would like to find the ancestors of sir andrew balfour as i am pretty sure that all of the other major houses of balfour are extinct in the male line. It would be nice to add some personalised touch to this work. I also believe that any descendant of andrew balfour would be the true heir to the title of balfour of balfour and not the present claiments, ie trenabie and fernie
once again, thanks for your input
