From the news:
This month, The Society of Genealogists have launched an interim database of their Memorial Card Collection, donated by Phillip Jones. You are now able to search the full Memorial Card Collection of 4,500 and 8,500 digital images. Mourners sent the cards after the loss of a loved one to distant family members, friends and neighbours announcing the death and giving details of the funeral. Cards like these can be used to build a family tree.
