1 By iel nna July 30, 2017 3:35 PM I think Matilda is a fine name. And if you or if she will be into nicknames, there's some options, Tillie (my fave), Mattie. I could even see Mat. Almost any name could be a middle. Do you use your surname or your spouse's/partner's? You could use your last name or your first, middle, or a variation. Or just something that may be special to you: literary, special place, etcetera.
