My Mom’s first name was Irene; my wife’s middle name is Irene, too! So it was natural to use Irene for our first daughter — Michelle Irene. My sister got “Lenore” for a middle name. But we couldn’t find a way to use “Gertrude” — it just doesn’t roll off the tongue nicely.
Just name a girl "Trudy" without the Gert. Makes me think of "Truly Scruptious" from Chitty, Chitty Bang-Bang, though.
