I have found the grave of Frances Kaneen - daughter of Alexander and Elizabeth in Alden Evergreen Cemetery - Alden, Erie County, New York. It is the same cemetery that contains the burial of an Esther C. Looney (wife of Robert) who died in 1849. I have just added Frances Kaneen to Find-A-Grave. There is also a large fallen monument to the right of hers. Unfortunately, it is upside down and cannot be read unless someone rights it. It is very large. I will include a photo of it with the Memorial for Frances on Find-A-Grave.
