What artist goes by the initials mew?

I have a painting with MEW. Mine is Mary Egbert White. It is an old painting of my mom as Little Miss Muffet. Mary is the 1st cousin one removed from my mother. Her husband was John White an olympic rower, and they owned a cat named Boompah after my grandfather. That's literally all I know. Not sure if it's the same, but hope that helps out!
