Hi,
Mary Duke was my Great Grandmother. After John Duke died she went on to marry Joseph Casagranda, my great grandfather. I actually have some photos of John, William and Janet (b: 1901) Duke that I inherited from my Grandmother.
There's a few typo's above:
John Duke was a Pumping Engine Keeper from Maybole Ayrshire
Mary Duke was from Mauchline Ayrshire
John Duke was from Mauchline Ayrshire
