I handle things similarly, but over the years have found a need for unique
identifiers for unknown persons and a guesstimate for their year of birth.
This is the system I use - for what it is worth. As names become known
their "bbb" identifier can be recycled and so far I have not needed more
than the 18278 unknown individuals available using this three letter
identification system.
CONVENTIONS FOR "UNKNOWN" NAME ENTRY
Unknown First Name: enter "?am" for a male, "?af" for a female, "?au" sex
unknown.
Unknown Last Name: enter "??abbb" where "a" in both "first" and "last" names
is a single capital letter code giving the approximate 33 year span (a
generation) for the estimated year of birth. The century and codes follow:
Years Codes Years Codes
1200-1299 A,B,C 1600-1699 M,N,O
1300-1399 D,E,F 1700-1799 P,Q,R
1400-1499 G,H,I 1800-1899 S,T,U
1500-1599 J,K,L 1900-1999 V,W,X
2000-2067 Y,Z
"bbb" is an entry sequence code that starts with "a" through "z", then "aa"
through "az", "ba" to "bz" etc. An example using a female with unknown
first name, born about 1750, who is the 54th person with unknown last name
would be entered as "?Qf ??Qbc".
Formula for arriving at date code for b.(birth) to use with unknown name is:
1. Use b. if known
2. Use b. of spouse, or spouse of spouse (other wife etc.)
3. Use first m.-25
4. Use bp+33 where bp=b. of parent
5. For bp use bc-33 where bc=b. of child in next generation
For bc use bp+33 where bp=b. of parent in previous generation
6. Use d.-65
8. Use dp-32 where dp=d. of parent
9. Use mc-53 where mc=m. of child
10. Use 33 years per generation from any known date.

Thanks for those samples, David. What I could not quite figure out is
how you are using the FIRST NAME and LAST NAME fields, from your
examples, but it gives me the idea of what you are doing. Thanks, --Jerry

Jerry,
Here are a few samples. They are from my main database from a different
program, But, I do the same thing in all of the programs I run. Yes, the
person index has all of these people at the top of the index, as the "("
comes before any of the letters. As you can see there can be many
different combinations, but they work for me. I use a GEDCOM to go from
my main database to Legacy and other programs that I have installed.
