Working on a very, very large complex family tree with lots of half, step-siblings, parents, and children.

Descendent father and 1st wife have children.  Father and children are direct descendants of family progenitor. 

Descendent father and 2nd wife have no biological children.  However, they have 'taken in' (fostered) orphaned children from 2nd wife's family.  2nd wife and fostered children are not direct descendants of family progenitor.  HOWEVER, they are living as one family with descendent father, 2nd wife, and descendent children/siblings.

I created another GenoMap for the 2nd wife's family and hyperlinked 2nd wife over to connect her to both Trees/GenoMaps.  I hyperlinked the orphaned/foster children from their GenoMap to my main GenoMap and connected them to the family tree as children of descendent father and 2nd wife.

THEN, I selected each Pedigree Line and changed the Pedigree Link from biological to foster child.

Descendent father's PROPERTIES window, FAMILY tab, shows his biological children listed first (numbered 1,2...), followed by the foster children (numbered 1,2...) and foster children are shown as having Other Parents in the table. 

2nd wife's PROPERTIES window, FAMILY tab, shows foster children (numbered 1,2...) and foster children are shown as having Other Parents in the table.

If I select any of the descendent father's children's PROPERTIES window, FAMILY tab, it lists their biological siblings correctly, but places the fostered 'siblings' as Half-Siblings.  I'm guessing they should be listed as Other-Siblings instead because of their foster child status.  (Choices Siblings, Half-Siblings, Step-Siblings, Other-Siblings).

When I generate the report entitled Descendants Report, the foster children are listed as children of descendent father and 2nd wife.  I can live with that, it isn't a major problem for my purposes and they were all very young when they merged into one family and refer to one another as brothers/sisters (rather than step-cousins).

Aside from the FAMILY tab listing the relationship incorrectly as Half-Siblings on the descendent father's children's PROPERTIES window; here is the second problem:  If I select the first male ancestor and right click: choose select > choose direct descendants, the foster children for this one family are included as direct descendants of the family progenitor.
