Where did Adaline's money come from?
Did I miss something? Did she get a big payoff when her husband died on the Golden Gate Bridge? It takes a lot of money to be able to just up and leave a job and home and start over again. Plus all of her homes were pretty big and nice, which in SF is very expensive. She didn't make that kind of money being a librarian. There was the one scene at the bank when she had a flashback that alluded to her making some money off of Xerox stock, but she'd already been around awhile by then.
