It’s important to go over your records very carefully. Review every printout, photocopy, note, and Internet record. Know what you have and what you don’t have, and make a to-do list of what to find. The basic genealogical advice is to work from what you know to what you don’t know. Please do not take your entire notebook; rather, take key notes that will aide in your search during the trip. If you are bringing your laptop, you may already have all the details electronically.
Remember there are records available in the United States (such as parish records at the Family History Library in Salt Lake City, Utah). Concentrate on what’s not available here.
