Hello All, I have a James Clanachan died 1873 at Crichton Sanitorium. His son also ended his time on earth in another sanitorium some 50 years later. Now, before you ask, I am not particularly worried about the gene pool. I an just wondering if there is a link as they both worked at the Waulkmill in Kirkcowan . What chemicals were used in the processes of making cloth in the 19th century? Ken Parker
