Comparative timelines can be used to compare two or more people/families. For example, the objective may be to determine the migration of two separate families joined together by marriage. A timeline showing both families will help to focus the research.
Unlike a basic timeline, a comparative timeline shows each year, whether there is an event or not. Constructing a timeline whether simple, detailed or comparative, can help illustrate gaps of time. The timeline can help determine where to look for records.
You can take comparative timelines a step further by adding additional family members or associates to the mix. For example, you could follow, and ultimately compare, children, siblings, in-laws or even neighbors, to see if other connections can be made.
A comparative timeline is also useful when trying to sort out identities. Sometimes we run across instances of name changes or aliases, and of course, we all have those female ancestors with unknown maiden names or parents. A comparative timeline can help you track each of the individuals to see if any fit the pattern to be your ancestor.
