That a child is taken from a family does not mean that it is not still in the family tree and since you have no newer photos you will have to make do with the latest you have. The same goes for a genealogy page in real life.
In a real genealogy page there would be more info like a birthdate but since that is not possible in the game there is only the image and since that can no longer be updated you have no track of when you taken away sim ages. That can unfortunately not be helped.
Okay look I'm not going to reply to you anymore because A. You're not getting it clearly and B. No offence but your answers are dumb. You can't tell someone how they want to play and see things. This is an error not something made on their part for what you are describing. You won't convince me. Bella out.
