descent or genealogy diagram

[Tim Bates]

anybody drawing the kind of trees used in genetics research where you have 
circles and square for female and male subjects, then marriage is a horizontal 
line joining two people, and children come from a vertical descending line 
bisecting the parental join-line, followed by a horizontal line to which  
children (squares and circles) are joined by further vertical lines?

I can manually get this design, but it is very cumbersome. What would be nice 
would be to have:

1. Magnets on lines (can't do this?)
2. Auto distributing magnets (so when a new magnet is added, the others move to 
evenly distribute themselves along the line

Any way to emulate this, and or any hope for this in a future version?

Genealogy is a large market in diagramming, and a very large consumer market.
