My maiden name is Robinson and DH's mum is Robyn. I would like to use Robin as a middle name for our daughter and he wants it to be Robyn. His argument is that I'm already not having Robinson and so actually Robin doesn't fit Robyn or Robinson, whereas Robyn is still a nod to my maiden name but is actually his mum's name and a better girls' name.
I actually prefer Robin anyway, as it makes me think of nature and the bird ❤️
