Have you really learned about the records in that "new" area in which you are researching? Don't assume that records in one location are the same as in another. When I started my late 1700 research in Virginia in never dawned on me to ask for a marriage bond. I had never used them in the upper Midwest, so I never thought to ask for them.
Had I read a basic Virginia guidebook or research outline, I would have been aware of them. Now familiarizing myself with the basic sources in a new area is one of the first things that I do.
