My mother hates our top baby name.

Sorry in advance for being wordy, there's a tl;dr at the bottom. My husband and I are expecting our second baby. We don't know the gender yet but have a slight conundrum regarding our top boy name and my mother's extreme dislike of it.Some background: We previously decided our top 3 names when we were expecting DS. We used our #1 boy name with him and want to go with #2 if this baby is also a boy. DH and I have liked this name for years, it's a pleasant but not overly used saint name, and it flows well with our uncommon last name. We'll say "Peter" for the sake of story-telling.Now my mother is very pushy about her opinions and name associations. She was quite bossy when both my sister and I were pregnant, telling us to use her favorite baby names and not ours. 3 babies later, she has yet to like a chosen name until after the baby was born and it "grew on her." She actively discouraged us from using DS's middle name because it was her disliked BIL's name (even though we were naming him after our favorite pope, not a long dead uncle. I can't help the fact that they shared the same name). Much to her chagrin, we named our babies the way we wanted to each time. So I'm already a little biased here.She's also complained in the past about how she couldn't believe my aunt named my cousin "Elaine," knowing that my grandmother despised that name. (Apparently my grandma was bullied by an Elaine and until her dying day, she disliked my cousin because of that negative association.) My mother thought my aunt should've respected my grandmother's wishes and chosen a different name, while I think grandma should've gotten over herself instead of punishing an innocent child.Back to my conundrum. When we mentioned 'Peter' as a potential name with DS, my mother had an immediate overwhelmingly negative reaction. But! She wouldn't actually explain why she disliked it. She just hated it and to please go with our first pick.When talking about it with my sister later, she said that she's pretty sure it's the name of the man who assaulted my mother when she was deployed overseas 30 years ago. My mother's never discussed with me what happened, nor do I think she realizes that my sister shared this information with me initially back in college. So I'm kind of in a pickle here.My mother and I aren't close. We've never been close due to reasons and while I respect and love her for being my mom, we're never going to be friends. My husband is in the military so once we PCS next year, we'll only see my parents for the holidays. She's realistically not going to have a super close bond with my kids, regardless of their names.So if we have a girl, there's no problem. But if we have a boy, we might. I wouldn't normally care about my mother's feelings regarding baby names, considering her past behavior and our distant relationship. She had her chance to name her kids, now it's our turn.But I'm asking myself, is it wrong of me to dismiss my mother's feelings regarding this particular name, considering she's never talked about what happened, plus it was 30 years ago? Is this an opportunity for her to turn a negative name association into a positive, or will she dislike her grandson forever because of it? I'm not sure what to do.Thanks for your helpful input, fellow Redditors.tl;dr: my mother hates our top baby name for personal reasons, not sure if I should consider her feelings or not via /r/Parenting http://ift.tt/2g8GNrP
