2028 Bride

Although I have been doing more of the research than my fiancé (we have discussed guest list, possible venues, etc. but I have been putting different lists together and I need some advice in terms of a guest list. I broke it down into two tiers, the second one being distant family. I am close to the family members on my mom's side, but I haven't seen any family members on my dad's side in a long time (would be 10 of them). I feel obligated to invite them only because it would feel right for my dad. I'm having a tricky time putting that together, any advice would be great!
