I was happy to find this thread about the Robertson/Gillon connection. I have David Gillon's wife as being Jane Robertson instead of Janet.She was my great great grandfather's sister. In a bunch of old family photos that my father has I found one of "Robert and May."The photo dates from between 1908 and 1918.The photo also says "To Uncle John with kind regards."I believe that Uncle John is John Duncan Robertson, Sr., Jane (Robertson) Gillon's sister.I also believe that Robert and May are Robert Robertson Gillon and Mary May Gillon. I scanned the photo and would be happy to send an electronic copy to anyone for whom the photograph has meaning.Please email me at firstname.lastname@example.org I would also like to know if anyone can provide information about how Jane Gillon died or where she is buried.
