How Do I Analyze the Results?
Compare each result from your search with what you know to determine if there is a match. This may require viewing multiple records or images. Keep track of your research in a research log.

I Found the Person I Was Looking For, What Now?

 * Add any new information to your records
 * Use the estimated age to calculate a birth date from the enlistment or muster in date
 * Use the age and location of the military unit to find the soldier’s family in census, church, and land records
 * 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 brothers, father, uncles, and cousins who may have served in the same unit or a nearby unit

I Can't Find the Person I'm Looking For, What Now?

 * 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
