I logged in to ask this and saw two other similar threads! I forced the title "Nana" on my mother because her side is always Nana, Shaun's mother is Granny because she says so. My father hasn't met Jacob
but I assume he will be Grandpa like his father (though I'd love him to be Poppop like my mother's father), and Shaun's father died when he was a baby. She has a partner of about 20 years, but he was never even close to a father figure to him or his sisters. I guess Jacob will just call him by his first name, but that feels strange... I had to call my mother's cousins Aunt because of the age difference.
