Geneology tracking

P: n/a
Does anybody have code for real geneology tracking through many generations?
And maybe an associated family tree report?

The example at:
http://allenbrowne.com/ser-06.html
is suitable for biological parentage only.

Human genealogies need to handle adopted children, multiple marriages,
children not of a marrigage, unknown parentage, maybe even people who
undergo gender-changes and so have date ranges associated with their gender.

You also need a fairly involved set of rules to be able to imply
relationship that flow out of the relationships you store. For example, if
Alex is the adopted father of Bill and the biological father of Clara, and
Debbie is the biological mother of Clare and Esther, what relationship
should be implied between Bill and Esther? Bill and Clara? ... Which
relationships do you store? And how do you handle the SQL for searching on
the implied relationships as well?

Allen,

I understand what you are saying. Actually, I need one for animals, so all
of the possabilities you listed in the your first pargraph don't hold true
for me.

For tracking animals I only need to track parents and grandparents, great
grand parents etc.
