  Mama had chosen the name Lark. Lark Browning Erhardt. Papa had wanted to call me Beverly Mary; Mary after the Blessed Virgin. Mama said she wouldn't hang a name like Beverly Mary on a pet skunk. Where she got the idea for Lark, I don't know, though one time when I asked, she said that larks flew high and had a happy song.
