This can make it difficult to understand where your ancestors’ information is kept.

Reading a Idaho map from the time period you are researching can help tremendously in solving these problems by leading you to the correct town records. It can also give you other leads, such as the location of city directories or old post offices in Idaho.

Choosing the Best Idaho Map – If you have a large source of maps to choose from, try starting with the area where your ancestors resided and looking for the maps with the most detail.  You can determine a lot by seeing if the area was still rural or more developed, and how far it was to the nearest city.  This can shed light on your family’s lifestyle and occupation. Were they farmers who lived in the country, or merchants who traveled often to a nearby city?  A map can give you an idea of what occupations were possible.
