Here's a complex little alphabet name game for you.

This dad seems determined to populate the planet. With each of his successive wives he has at least 5 children, (probably including some twins and triplets) for a grand total of 26.
Rules:
1. Roll the 6-sided dice for the baby's gender. Odds for boys, evens for girls. You can run them one at a time or set it to roll multiple dice.
2. Parents first names: Choose the A-Z letter dice and 3 dice. Roll for first, middle, and last initials for the dad and each of his 2-5 wives.
3. Kids first names are a twist on Duggar-style naming. Within each group of siblings, each gender shares a first letter with mom or dad's first or middle names. So, for example, maybe boys use mom's first initial and girls use dad's middle initial. The letters change with each wife's set of children.
4. Middle names run the course of the alphabet. One gender begins with Z and works backwards, and the other gender begins with A and works forwards. So, baby #1 will either have A or Z for a middle initial, and from there, each letter of the alphabet will be used once.
5. Give your family ages as well. It might be easiest to work backwards from the last baby...
Hope this all makes sense. I'll post mine as an example. Have fun!
