Send a message to the person who requested a photo of the grave monument of Blanche G McIntyre Calvert with the following comment:
I am researching a Calvert branch that connects to my tree. I am hopeful this headstone photo might have actual birth and death dates. I am almost 100% certain this is the David John Calvert I am looking for. Thanks for your website, it is greatly appreciated. I personally understand the time and effort put into taking headstone photographs. I have put hundreds on Find a Grave. Scott
