The cemetery card gives him as son of George and Mary LeBlanc, born Ireland circa 1840 from his age. I suspect an error with his age, it is more likely to have been 38 than 28
He is buried in the same grave as his sisters Maria, Harriet, and Mary Ann in Spring Grove Cemetery, Ohio. Charles did not marry
Apoplexy is a medical term, which can be used to mean 'bleeding' in a cerebrovascular accident. However, without further specification it is rather outdated, and is today rather used for specific conditions, such as pituitary apoplexy. Historically, the word "apoplexy" was also used to describe any sudden death that began with a sudden loss of consciousness, especially one in which the victim died within a matter of seconds after losing consciousness. The word "apoplexy" may have been used to describe the symptom of sudden loss of consciousness immediately preceding death and not an actual verified disease process. Sudden cardiac deaths, ruptured cerebral aneurysms, certain ruptured aortic aneurysms, and even heart attacks may have been described as apoplexy in the past.
