Send a message to the person who requested a photo of the grave monument of David Bertram with the following comment:
I have been researching my family for many years now and have not been able to locate or enlist the assistance of Bertrams in Scotland. This is probably more through fault on my part on not knowing who to talk to. By providing my name on your website I hope that this introduces me to family who may not be associated with the sites I have previously utilized. Thank you for this opportunity.
