How come Lucy hasn't been mentioning Regina (Roni) being Henry's mom o Rumple (Weaver) being his grandpa?

I mean she only seems to mention her being Henry's daughter and Jacinda (Cinderella) being his true love. I've asked this on Twitter and Youtube to no response. I really wanna know. Why hasn't she brought up Henry's other cursed family? I'm honestly really enjoying season 7 except for that part. Does she not know about Regina o Rumple o Hook o even Emma?
