My cousin had a baby last week on my nieces birthday. They named her a different name to my niece but both will go by the same short version. Think Isabel and Belinda both going by Bel. Both children are unlikely to ever meet, we aren't close to cousins but we are a tiny family. There are now 15 of us total so whilst they wont grow up together its very obvious they have the same name. Cousin has made it clear the new baby will be called by the short name.
What is upsetting us is my niece isn't biologically my brothers nor are my brother and nieces mum married however they've been together 8 years and my niece was 3 when they got together. In that time my auntie has had 4 grandchildren and we've always sent birthday cards, bought Christmas presents for the kids and my niece has had nothing from my auntie or that side of the family. It makes me wonder if they would have used this name if my niece was biologically my brothers. Aibu to be upset over all this
