In Denmark that is the case. Plenty make new surnames for their family. Double barrel or keeps their birth name
For me my very Danish birth name is slang for penis in English I wasnt keen to keep that. (However I had a lot of why dont you double barrell) dh has pretty standard Scottish surname nothing fancy we used that
I am one of 17 cousins on my mothers side
Breaking that down with youngest cousins in their 30s oldest in their 60s
Not married. 1 female who is divorced and kept her name in 1st marriage. 5 men some of those in long term relationship with no intention to marry
Kept name 2 women 0 male
Changed name 3 women 1 men
my sister and I both with the surname that means penis in English slang we both married British men meaning 1 in Denmark changed and she has kept her birth name as a middlename.
Made new surname 2 female 1 male
Double barreled 0 females 2 males
When I glance facebook on old school friends it is about 50/50 who still has only the surname they had at school most have double barreled their names. 1 guy has changed 5 times and I know is only on 2nd marriage never asked him why the changes.
Dd1 is getting married they briefly disgussed double barrel but as their surname both start with same letter they decided against it (Think Smith-Saunders) and drew straws on who was to change. Dd is changing. Her sister in law to be did not change on her marriage 2 years ago her 2 daughters have both mums and dads name.
I think it should be personal choice. I lived in the UK for 6 years as Ms Penis it was not fun I was happy to change it.
In Danish my birth surname means a chef.
