Otherwise, I’ll list the heirs here.
Marc & Ashley Jacobsen. Ashley was a creative, artsy sim who seemed to pick up many skills quickly. Marc was a a sim who wanted to be great at his career, but knew the most important thing in life was family. Ashley would have been happy with just a couple kids, but she loved her man and he wanted a house full, so they ended up with 5. Penelope, Felix, Sebastian, Calvin & Clara.
Generation 2 heir & spouse:
Calvin is basically your ultimate outdoor sim. He’s friendly, he loves nature, he’s an angler.. which plays nicely into his LTW to have the perfect aquarium. His gal Maisie is his soulmate. They were inseparable pretty much from the time they met. They have three children together – Poppy, Basil, and Rosemary.
Generation 3 heir:
Basil is our quirky little sim with a real penchant for building things, but he’s interested in many things. His dream was to max out 3 skills, and he hit that with no problem. He married Kitty, who was his perfect complement. A lot more down-to-earth and organized than he was, the two balanced each other perfectly. Together they had twins Liam & Molly.
