I have a question/questions about marriages / remarriages and adoptions.

But first let me ask stuffs about marriages / remarriages.

<1st Scenario (Marriages / Remarriages)>
A. Let's say there is 2 families (Town Families, aka Non-Service Families, aka Playable Families):
1. Family 1: Husband, wife, and baby (will grow up as toddler and beyond)
2. Family 2: Husband, wife, and baby (will grow up as toddler and beyond)

B. Let's say wives from Family 1 and Family 2 dies of something.

C. So, after few Sim Days (which I would normally consider 1 Sim Day as 1 Real Life Year), both husbands from Family 1 and Family 2 remarries to separate woman with Active Sims (Women) that I play as Active Family/Household.

D. Then what will be 2 husbands (widowers)'s babies/toddlers?

E. Will they be considered as stepsons?

F. How the Family Tree will show up?

Now for the 2nd part

<2nd Scenario (Adopt Babies/Toddlers from 1st Scenario)>
A. Let's say there is 1 Active Household/Family (All Sims in this Household are Roommates)
1. Woman 1: She knows (Best Friend) all families members in "1st Scenario
2. Woman 2: She knows (Best Friend) all families members in "1st Scenario
3. Man 1: He knows (Best Friend) all families members in "1st Scenario

B. So, after few days passed since wives of "1st Scenario" dies both husband (widower), married with 2 women in "2nd Scenario", aka my two woman in Active Family/Household, now both husbands from "1st Scenario" dies of something.

C. Now the question: Can my 2 women from "2nd Scenario" can adopt the 2 kids (Baby/Toddler) ?
