I love it. It has a bit of spunk to me. I have two Matildas in my family tree, so I grew to like it over the years.
From your PNL I think it sounds great with these as siblings:
Adelaide, Agnes, Arthur, Astrid, Beatrice, Daphne, David, Diana, Douglas, Eugene, Frederick, Jane, Joanna, Josephine, Julia, Katharine, Louisa, Olive, Olivia, Pamela, Pauline, Pearl, Philip, Richard, Roger, Simone, Susannah, Ursula
