First name for middle name Shirley?

[jaychops]

I want to give our DD2 my Grandma's name Shirley as her middle name but struggling for ideas for her first name. DD1 is Elizabeth if that helps!

I have an Isobel Shirley after my Nan which I think works well x

Isabel/Isobel lovely but I don't think you can have both an Isabel and an Elizabeth as they mean the same thing...
