This is my sister's name, so when I saw the subject I just had to respond.
I think that Patricia is actually a pretty name. Not boring and not all harsh, in fact, it's rather soft. Not plain. But definitely dated.
The problem I have with it is the nicknames. My sister is always called Patty, never Patricia, and I don't care for Patty at all. Tricia is better, but I'm still not nuts about it.
Patricia was once very, very, popular. There are a LOT of Patricias out there. But the vast majority of them are now at least over forty. A little Patricia would stand out now. However, it seems that most people want to avoid a name that is dated to the present day's middle-aged and old women, which Patricia sure is. We have to wait for all of the Patricias to pass out of this world for Patricia to have a chance at a comeback.
But what the heck, I'd say to anyone who likes it, go ahead and use it!
BUT...Rose is very unoriginal as a middle name.
