Keeping the name Uthmaan and name having an effect on the child

Q: I wanted some information regarding naming my son Uthmaan after the Sahabah Uthmaan bin Affan (radhiyallahu anhu). We have heard a lot of good about this Sahaabi but wanted Mufti Saheb to share some information regarding him which is authentic as well as if you can send information regarding the meaning of Uthmaan. 

I also wanted to know, does the meaning affect the child or if the child is named after someone will that affect the child? 

Woman having all her meals with her mother in law

Q: My husband, my mother in law and myself live together. I don't have a full kitchen of my own but I have kitchenette upstairs with the basics - fridge, toaster, kettle and microwave. 

In Ramadhan, my husband says we should all 3 have sehri downstairs because his mother shouldn't be eating alone. I responded saying that if he would like he can go downstairs for sehri but I will be having sehri upstairs as I don't see why I should have all meals together all the time. 

Islamically am I entitled to have some meals separately. Please advise.
