Taren, here is a link to an online article that discusses Mary Queen of Scots and Marfan’s syndrome:
http://www.bbc.co.uk/dna/h2g2/A3065140The online article references an article in a medical journal which unfortunately does not seem to be available via the internet.
Marfan’s syndrome may well have affected Mary Queen of Scots and many of her descendants, but it seems probable that those who had it suffered from mild cases based on their causes of death, since few of them died from heart problems.  Many of them lived long and physically active lives, which would not have been possible if they'd had a severe case of Marfan's syndrome, while several of her female descendants had large families, which, again, would not have been possible if they'd had a severe case of Marfan's syndrome. Â
All that aside, many of Mary Queen of Scots' descendants were remarkably tall. Â The length of their fingers is difficult to judge, because prominent artists like Van Dyck often chose to use hand models, so the hands you see in his portraits are not necessarily those of the sitter. Â
Minette and William III suffered from scoliosis/hunchbacks.
Mary Queen of Scots, James I and VI, and Queen Anne suffered badly from arthritis.
Queen Anne had lifelong eye problems.
Thank you so much for coming out of lurkdom and posting. Â
