I wish English would hurry up and find words to describe the following relationships:

Your ex-spouse's first spouse
Your ex-spouse's first spouse's children with a new spouse
Your daughter's step-child from a former marriage
Your ex-step-parent's parents
Your step-sibling from a stepparent's previous marriage
Your former step-sibling from a stepparent's previous marriage
