A more experienced researcher gave me some advice when, as a novice genealogist, I became frustrated when faced with a brick wall. "Back away," she said, Put that family aside and work on another family for at least a month. Then go back to the first family and you will see things you missed before." She was right and this technique continues to be one of my main strategies when I become frustrated in my research.
Try it. You may just find it will work for you, too.
