This isn't news, I've done this for decades. I have a fake family that I use for Mom, pet's name, fathers birthplace, etc. But unlike the OP, I only have one

This isn't news, I've done this for decades. I have a fake family that I use for Mom, pet's name, fathers birthplace, etc. But unlike the OP, I only have one fake family to track. It's not hard to do, just pretend you are an undercover KBG agent. Alternate plan is to just rotate family by one, so Dad moves to Mom, Mom moves to older sibling, etc and the pet rolls to the top (Dad).
