    I file my charts alphabetically, but I believe there is a numbering system when you print them out on Family Search. I suggest you print out a pedigree chart and notice the numbers on the chart. The 5 generation chart has 31 numbers/people as the primary couple. I hope this helps you. Others may have better suggestions, so you may want to post your question on another group, possibly the Family Search Tree group? Or Basic research group? Good Luck with your Continued Research, Pam Whicker

    note that the TOP person on each generation will have the correspondig number shown below.

    Also - that same number is the number of people in that generation

    You can see how eventually this number quite explodes

    the mathematical equation turns out to be: Number = 2^(N) - where N is the number of generations

    i.e. 2 to the power of the Nth generation (assuming you count your parents as the 1st generation)

     

     

    You 1

    Parents 2

    Grandparents 4

    GGrandparents 8

    GG Grandparents 16

    GGG Grandparents 32

    GGGG GRandparents 64

    GGGGG GRandparents 128

    GGGGGG GRandparents 256

    GGGGGGG GRandparents 512

    GGGGGGGG GRandparents 1024

     

    So - why are you so interested in this number?

    as a sorting routine?

    also note for each generation half of the numbers belong to the paternal side and half to the maternal side - so if you want to know the number for the first maternal Grandparent at that level - simply divide the number above by 2 and add it to the original number

    at generation 2 it is 4 + 2 =6

    at generation 10 it is 1024+512 = 1536

    Of course that structure only works if you are not tracking BOTH biological and adoptive or step parent relationships. Then the regularity of that pattern falls apart.

     

    There ARE a couple of formal numbering schemes that have been created for Genealogy recording over the years, but their names escape me now as I've not needed to ever use them.

    well . . . if you were a person who was adopted

    you could have one set for adopted lines

    and one set for blood line

    yes - there would be duplciate numbers between both - but I dont see that as a drawback.

    The  AHNENTAFEL CHART numbering system - uses the same numbering system

    see:

    and an exampler:

    Yea, when I referred to "a couple" of formal structures, I had forgotten that the Ahnentafel method was pretty well the only "ascending" type structure (i.e., the typical pedigree). Almost all others are descending systems. But in general they were all originally for tracing of genetics rather than the more general "families" (like those supported on the FS FamilyTree). Here's a good reference though:

     

    https://en.wikipedia.org/wiki/Genealogical_numbering_systems

     

    If you are talking about segments of your tree (e.g., a collection of pedigree charts each with only 3 or 4 generations on it), then each chart has to have its own number that is unique, and may or may not be related to the numbering within the charts. This was the dilemma that folks have with the old pedigree chart sheets that were used for family history books. In this case I know of no formal structure. I had invented one for my own use at one time, but it was complicated and still didn't handle the non-genetic linkages when they were there (i.e., it was binary as well)

     

    At this point if I had to do it again, I'd probably base it on the root person in that specific chart (e.g., use the RIN or the FS PID numbers). That way it would tie back to the preceding chart regardless of what it was.

     

    Here is some information on another variation that is being used that works for both ancestral as well as descendancy

     Note that this one can support multiple marriages:
