* numeric scheme for descendants, does it exist?

[Ron Melby]

in ancestors the SOSA number is easy to create, and as a single number contains all sorts of information, and trivial to sort on. *****AND FAST TO COMPUTE*****

Mike,
if you recall this thread:

I have searched or quite some time and cannot find a system like SOSA for a descendancy list, and SOSA does not have a number schema for 'ancillary' relations (those not sanguine) such as uncle. And the issue with d'Aboville or Huntington numbers is their collating and decollating time and code to sort. the dot numbers at the far end would have to be known or estimated (or each dot separation kept track of for max, so that one could run thru all over again and set their array elements so they are right justified and each descendant having the same number of elements. I dont know if I am making sense, but the time of that would be prohibitive. Is there a system I am missing because I don't know its funny name?

I believe SOSA (Sosa-Strandonitz System) is the same as the Ahnentafel numbering available in FH.

See Genealogical Numbering Systems and How to Use Them that describes Ancestral Systems: The Ahnentafel System and Descendant Systems including The Register System, The NGSQ System, The Henry System, and The d’Aboville System (some of which are available in FH Outline Reports > Descendant Outline). It goes on to explain how to combine them to cater for indirect relatives such as uncles, cousins and adoptive relatives.

See Wikipedia Genealogical numbering systems that covers similar numbers and a few more.

I am at least surfactantly aware of those systems.

for sanquine descendants, an integer can be used, but cosanginity in those systems (near as I can tell) require non-numeric or 'dot' extensions to map. I have tried by binary number the d'Aboville or Huntington, but it (as is) will duplicate numbers, i.e. numbers are not unique. Never mind loops where there can be more than one number, I am simply interested in 1st relation,
