The Great-Greats

Back in September, Molly met her Great-great aunts and uncle. Super special.
From Left to Right...Great Grandpa Homer, Great-Grandma Belle, Great-great Aunt Isabelle, Great-great Uncle Connie, Great-great Aunt Linda, and Great-great Aunt Wanda...and of course, Miss Molly
Can you tell who the brother and sisters are?
(Grandma Belle, Aunt Isabelle, Uncle Connie, and Aunt Wanda. We were sad that Aunt Peggy couldn't make it.)
