Pedigree Analysis Steps One to Three - International Institute

Pedigree Analysis
When starting ancestral research, and as you move back each generation, carry out the procedure known as a pedigree analysis. This consists of three stages:


 * 1) Organizing the facts that you have
 * 2) Estimating dates and places
 * 3) Planning the next research step

1. Organizing the Facts That You Have
The following chart shows part of my pedigree with the known facts organized in standard fashion.

2. Estimating Dates and Places
Here we make some hypotheses by using the known facts and some estimates to provide a framework of dates and places with which to start searching for more information. We recognize that one or more may be incorrect, but we say to ourselves—if these assumptions are true then these are the most likely dates and places. The following chart shows our estimations and the 2nd chart adds these to the pedigree.

Pedigree Analysis: Step 3- Estimates Added

Now we have some concrete ideas of when and where to start our searches.

3. Planning the Next Research Step
Choose an ancestor and decide what source(s) would give you the needed information. Take into consideration the following:


 * Is there previous research that can be checked, for example the Ancestral File or contact with other researchers through genealogical directories?


 * Are there any indexes to original sources which would assist you? Examples are the Scottish OPR Index or probate indexes.


 * Can you conveniently access these indexes and the original sources? Or will you need to get someone else to look at them for you? Is it cheaper to do the research yourself by visiting the archives, on film at your FSC, or by using a record agent at a distant archive. Consider travel expenses and cost of time, films, library fees, and record agent fees.
