My art ignorance led me to finding out more about this artist and here is one of life's coincidences ...........this talented painter married an Agnes MacDonald who turns out to be the sister of Georgiana who married Edward Burne-Jones - William Morris's lifelong friend and business partner!! http://en.wikipedia.org/wiki/Edward_Burne-Jones
On the left is Edward Burne-Jones & the right William Morris
And one of the MacDonald sisters, Alice fathered Rudyard Kipling; http://en.wikipedia.org/wiki/Rudyard_Kipling
Next blog I have an even more bizarre coincidence
that you will not believe is true - stay tuned!
