I do feel pioneery and religious about it.
I can't see using it as anything other than a middle name, if I were really prioritizing
Mercy at that point in my life. I think
Mercy is a really fabulous virtue, and it's a pretty sound and a cute-looking name. However, it brings to mind suffering and penitence, so it's too solemn for my taste. I think I'd like it on someone else though.
