Send a message to the person who requested a photo of the grave monument of Henry Trembath with the following comment:
I have been doing family research for many years. While visiting Walhalla a couple for weeks ago, noticed his name on the death register at the mine when doing a tour. Recognised the name Trembath and took notes to check when home. It turns out William Henry Trembath 1844 - 1870 is my husbands 3rd cousin 4 times removed. To be connected to the history of Walhalla is remarkable.
