Is there a box for "All of the Above?"
Margaret is such a terrific name. It runs the gamut from meat-and-potatoes sensible to lady-of-the-manor refinement. And the nn possibilites are endless.
From your list, if I have to choose,
Margaret Helen gets my vote just to see the look on your mother's face when she learns. :-)
Margaret Elena would be s nifty twist if you're still not settled.
I try to avoid using
Georgia in the mn position.
Margaret Georgia sound more like a place than a name. [But I'm odd that way. It may come from the fact that here in
Washington State (U.S.) we have a town named
George,
Washington.]
Personally,
Margaret Alice is my favorite combo.
Margaret Cecily and
Margaret Eleanor round out my
Tudor Megs nicely.
