I am almost done filling in my front page.
Lessee. We have... The Blackburns!
This one will be fairly short. I don't know why they never had children of their own, but Anabelle Blackburn just didn't want to have children, so she didn't. The husband whose name I can't remember did, however, so he adopted Ava Tinsley's daughter Ashlynn. He also had his son Gino, but I can't remember who his other parent is. (I think it might actually also be Artemis. That would be hilarious.)
Both of them were musicians, with Lady Blackburn taking the classical route while husband eventually quit and stayed home to keep the children.
Their marriage was rough, but they stuck it out. She made lots of local friends to make up for the lack of connection with her husband, and he put his all into raising his children, teaching them as much as he could.
The house went to Gino and his wife, one of the Falman sisters, and I think they have three? kids.
