 * Type of records in file

How to Use the Record
To begin your search it is helpful to know the following:


 * Name of the soldier
 * Other identifying information such as age, birth date and place, military unit, or enlistment place

Search the Collection
To search the collection: ⇒Select "Browse through images" on the initial collection page ⇒Select the "Document Type" ⇒ Select the "Surname Range or Military Unit and Surname Range" this will take you to the images.

Look at each image comparing the information with what you already know about your ancestors to determine if the image relates to them. You may need to look at several images and compare the information about the individuals listed in those images to your ancestors to make this determination. Keep in mind:


 * There may be more than one person in the records with the same name.
 * You may not be sure of your own ancestor’s name.
 * Your ancestor may have used different names or variations of their name throughout their life.

Using the Information
When you have located your ancestor’s record, carefully evaluate each piece of information given. Make a photocopy of the record, or extract the genealogical information needed. These pieces of information may give you new biographical details. Add this new information to your records of each family. The information may also lead you to other records about your ancestors. For example:


 * Use the estimated age to calculate a birth date.
 * Use the age and location of the military unit to find the soldier’s family in census, church, and land records.

Tips to Keep in Mind

 * If your ancestor used an alias or a nickname, be sure to check for those alternate names.
 * Even though these indexes are very accurate they may still contain inaccuracies, such as altered spellings, misinterpretations, and optical character recognition errors if the information was scanned.
 * When looking for a person who had a common name, look at all the entries for the name before deciding which is correct.
 * Continue to search the index and records to identify children, siblings, parents, and other relatives who may have served in the same unit or a nearby unit.

Unable to Find Your Ancestor?

 * Look for variant spellings of the names. You should also look for alias names, nicknames and abbreviated names.
 * Search the records of nearby military units.
 * Try alternative search methods such as only filling in the surname search box (or the given name search box) on the landing page leaving the other box empty and then click on search. This should return a list of everyone with that particular name. You could then browse the list for individuals that may be your ancestor.
