Continue this same numbering sequence for all generations listed in the Family Group Record forms. So the third child of the fourth child of my great-grandparents will have the code ‘S+4+3’. The plus sign (+) signifies a progression to the next generation.Įach child of the children of my great-grandparents are also numbered 1, 2, 3, 4, etc. So the fourth child of my great-grandparents (could be my grandparent or great uncle or great aunt) will have the code ‘S+4’. The code ‘S’ is then used to signify all descendants of my paternal grandfather’s parents-St Denis.Įach of their children, preferably listed in chronological order, are numbered 1, 2, 3, 4, etc. My paternal grandfather’s parents: SPC8/PC9. For simplicity, only add the Pedigree Chart reference number to the first code for the family and not to each of the subsequent descendant’s reference numbers. Fewer errors will occur.įollowing the first letter of the surname, indicate their Pedigree Chart reference number. I like using the first letter of the surname because this prevents having to look up a reference number to know which family group you are referencing. Use the first letter of their surname, if they are all different. If you wish to follow the family branches of your great-grandparents to include all your living relatives, here is the appropriate numbering sequence.Įach great-grandparents’ family is assigned an alphabetical code. There are many variations on such charts. A descendancy chart starts with a certain ancestral couple and comes “down” to you and living generations, including all children of all children. A pedigree chart is an ascending form starting with yourself, and only notes direct ancestors. Some of the children will be married while others will be single.īefore you can establish a logical coding system for your family branches, decide what you want to achieve. One family might have 3 children while another family might have 10 children. When you start looking at individual family branches, the pattern for each family is different. Your paternal grandmother would be acknowledged by using the reference number PC5.ĭescendants Reference Numbering System When using the reference number on subsequent forms add PC to the code originated from the Pedigree Charts. Notice that for each generation, the reference number doubles for the next father.ĭuring your research you will be using many other forms.The reference number for the great-grandfather of ancestor #22 is #176.The reference number for the grandfather of ancestor #22 is #88.The reference number for the father of ancestor #22 is #44.Ancestor #22 in the 5th generation is now transferred to a new form. Continue the doubling method for each subsequent father. To calculate the reference number for the father of this ancestor, simply double the ancestor’s reference number. Where the number 1 appears on the numbered chart, you would indicate the reference number of the ancestor in the 5th generation (16 to 31). Once you complete this chart, you start a new un-numbered chart. If you use the sample chart found in your course material, you will notice that only 5 generations can be listed on a standard “8½ x 11” sheet, in other words 30 ancestors. Mothers will always have their husband’s number plus 1. Notice that all male ancestors are even numbers and female ancestors are odd numbers. The numbering sequence on your pedigree chart will be as follows: If you are researching your entire genealogy, then your name will be reference number 1. The reference person number 1, will be the person whose genealogy you are doing. This chart will list all your ancestors from one father and mother to the next father and mother. Here is a description of the most commonly used coding system on Pedigree Charts. But a 10 generation list of ancestors contains 1,022 because this is the total number of ancestors for the 2nd to the 10th generation inclusive.Īncestors are traditionally recorded on a PEDIGREE CHART. The 10th generation by itself, will contain 512 ancestors. Start with yourself in the first generation. We all have:Ħ4 4th great-grandparents =Įach generation doubles in size. Let’s start with ancestors, since the number of ancestors are easily identified. Again you must be consistent.Īncestral Reference Numbering System
