Pen Names

I have a question! I mostly write under my real name Katherine Rochholz but I do have a pen name that some have said is easier to remember and I should maybe use that more, (I have only used it in local contests and things of that nature for poetry and flash fiction) Please tell me what you guys think about pen names :) By the way my pen name is Evelyn A. Rae ( yes that is how E.A.R. Publishing got it's name it is based on my paternal grandmother's first name (she went by her middle that is why I chose the first name) Evelyn. My maternal grandmother's middle name Agnes and my mother's middle name Rae :) Let me know what you think!
