Would this work as a sibset?
Absolutely!!!
Yes. [name_m]Henry[/name_m] is classic, [name_f]Rosalind[/name_f] is vintage. Both have history behind them, and I think classic and vintage names tend to complement each other well.
They absolutely work together! What myosotis said more or less sums it up.
It works great! I think of them as both being kind of vintage but stylish names.
Another yes. I love [name_f]Rosalind[/name_f].
Absolutely - both are very Renaissance-era names to me.
