Giving baby random surname?

[Libertyy]

Family background is religious, patriarchal in terms of family names so daughters don’t pass on surnames but daughters are meant to maintain their maiden name and not adopt a man’s name. However in this family the previous generations apparently had no clue about naming conventions so everyone got a random surname that wasn’t the actual family name anyway, the daughters got titles for surnames.

WIBU to give baby a random surname too?

I would follow the standard convention or legal requirement if there is one, of the place I was in.

I don’t fully understand the convention you’ve described but if it’s your baby I’d give them your name, something I regret not doing. One consideration is just that you will be easily identifiable as family for passports, communications with schools etc.

What does 'given titles as surnames ' mean? I'll admit I'm baffled by this convention.....

As a genealogist, your family sounds like a total nightmare!
