My name has affected how I named DS (and proposed name for DD, due in 2 weeks) in a big way.
I am 1 of 4 children myself, and we all have reasons for all our names (the 2 boys have 2 names+surnames, the two girls have 3 names + surname. We all also have confirmation names and I still use my maiden name at work!). The reasons are all linked to family history, family geography, M&D's favourite things, then the last child was a Z name! for this reason I just name my children a name just because I like it!
eg:
I am M&D's joint favourite literary heroine (they discovered this on thier first date) - Granny's name - Place in West Indies where Dad lived for many years.
DS is - Longstanding first name on DH's side, discovered when FIL was doing his family tree when i was pg with DS - Uncle who was dying but lived when I was expecting him - FIL.
DD will be - Variation on MIL's name - My name (in honour of my Dad, he spent his whole life collecting editions of this book, the weight of this name in my family is way beyond just being me) - Village where DH and I lived when we first got married.
Having lived with a awkward middle name (the west indian ones) and maiden name (irish, lots of vowels) and now having a lovely simple traditional English surname, both DS (and DD)'s names are normal, well known, unremarkable, spellable names.
