Hi,
Is it Robert Elder as opposed to William.
Ontario Death Record,
Elder, Frank Kilpatrick, b. Aug. 14, 1892 Glasgow, married, spouse Mary Isobel Dickson, d. June 10, 1944 Hamilton Ontario, occupation guard Westinghouse Co., father Robert Elder, mother Mary Jane Murdock, wife M. Elder was the informant, cause of death arterial sclerosis with occlusion, buried Woodland Cemetery, Hamilton.
Family Search should have this death but I can't find it.
Frank served with the Canadian Forces WW1, which give his dob Aug. 17, 1892, but confirms
his death as June 10, 1944. His file is very slow to load, 78 pages.
