Don't condemn your relatives for being packrats. Sometimes the materials they maintain can be the source of tremendous clues for your research. Ask your parents, grandparents, aunts and uncles if you may look through old letters and postcards for addresses and dates. Sometimes the dates and return addresses will help you locate or place a lost or missing relative. The contents of these written communiqués can provide additional details on their lives and those of other family members. This information may be just the missing link you need to make the connection to the next research step.
In addition, savor the images you find on vintage postcards. They may show the places where your ancestors lived at the time they were there, and that can provide you with a visual perspective of their daily lives. Picture postcards from places they may have visited and their observational comments on the obverse side of the card may expand your understanding of a journey they made. Either way, you are building the context of their lives.
