Have you read Ramsay's books and came to a conclusion that they are great work? Or do you just bring up the name because he supports your point of view?

You might want to check also some authors who have more critical view about history of the Bible, like Bart Ehrman.

Usually I look first for most recent authors if the question is about history. Ramsay died in 1939 and knowledge about history of Bible has been advanced after that. Maybe Ramsay had something interesting to say, but it might be better to start with more recent authors if you really want to learn higher quality information.
