When I married the first time,I kept my maiden name.My parents made an enormous fuss,saying I was no longer "entitled" to use it since I was now my husbands wife.They insisted on calling me Mrs 1st Husband.We hyphenated our surnames on dd's birth certificate.
When we divorced,I continued to use the hyphenated name.My parents expected me to return to my maiden name..
I married 2nd H and gladly took his name,just to get away from the whole thing with my parents.
When I divorced for the second time,I decided to use my middle name as my surname - had been g.g'mo,g,mo's and m's middle name.In fact,I changed my name by deed poll as soon as we separated.
Not surprisingly,my parents are offended by this.They refuse to use it and address mail to my first name only.
My middle/surname is Welsh,but my first name is not.Living in Wales,I am regularly addressed with my names the wrong way round,iyswim.But I am used to this now.
My 4 older dc all have different surnames to me.Baby dd has my middle/surname as her surname on her birth certificate.She has no contact with her father.
Other people - particularly when filling out forms,passports,at school etc - find this more of a problem than we do.
Nothing would induce me to change my name again.Eldest dd's have said they may choose themselves a surname when they leave home.
