NN's for .....

[Cewafwb]

......Savannah please and also second and third names to go with?

NN's Savvy? Anna?
Middle names Rose, Grace something shortish I think at least for the second name (two middle names are great btw, my DH and DS have 2)

NN Ava, Avi, Vanny, VV, CeCe, Vanna

Sassy

Personally I would have a traditional second name and then a one or two-syllable family surname as the third name, something like the following:

Savannah Amy Jensen
Savannah Faith Ellis
Savannah Mary Blake
Savannah Louise Grey
Savannah Victoria Leigh
