Thomas Wyatt Married Marye Waymothe

I have this marriage in 1603/4 (writtten this way because of the calendar alteration) in Brixham, South Devon. I think, as children, this couple may well have witnessed the Spanish Armada fleet sailing up the English Channel, and I am trying to find out something about status and occupation. Can anyone suggest the kind of research I should be following to find out more about how these families lived?
