My latest discovery is an old postcard (1905) of "The Cross, Kilsyth" that has been posted by Paris-Roubaix on flickr. The image is copyrighted, so I can't post it to my blog. In order to share this wonderful image, I have created a link in the sidebar of my blog. We now know that "The Cross" was at the top of Main Street, but I'm still not sure what the cross street was. Based on current Google Maps and an old map that I am comparing, the most likely cross street was Burnside Street. If anyone has any additional information, I would love to hear from you.
I have also added links for a 1950 postcard of the old parish church in Kilsyth and a 1907 postcard of the Burngreen.
UPDATE: Based on information received from Adam in the comments to my blog, I have updated my Google map of Kilsyth to include the Cross of Kilsyth at the intersection of Market St. and Main St. Paris-Roubaix has also posted a picture of this area that was taken last year. I have added a link to the newer photo in the sidebar. Because the upper portion of Main Street has been closed, the "top" of the street looked to me to be further down. I'm excited to have more accurate information! Thanks Adam and Paris-Roubaix.
