Be advised that I will NOT post a cause of death on any sites. That information is far too personal. It is true that it is a matter of public record, but one can look it up through the source material if they wish.
Please do not add death certificates to memorials I manage. I do not think they add anything to the site and will request they be removed when found. FindAGrave does not allow documents downloaded from other sites such as Family Search to be uploaded to memorials.
