I've been updating some records in a service directory this week, and I've come across a ton of hospitals with "memorial" in the name. I commented about how harrowing this sounded on Facebook, and a friend explained that this was often due to the way estates, wills, and major gift agreements are drawn up. In cases where a building is named posthumously, the "memorial" is often left out of the name. However, these affairs were more formal when many hospitals were created, so many of them retained the word.
And what of hospitals like Roxborough Memorial, or Delaware County Memorial? Well, these are often the result of multiple posthumous (or even community-wide) donations, where the names are left out in the pursuit of fairness.
(h/t to Christy for dropping some major memorial knowledge on me)
