I have Laura's family tree going back several hundred years. I'm still trying to trace the Bailey family.
I believe Laura's sister, Mattie married a Younger. 1900 Census shows Mattie and children living with John and Laura. She's listed as John's sister-in-law, a widow and her last name as Bailey. I have a picture of them @1910 with Mattie and more children, her name now listed at Younger. My guess is Laura and Mattie married brothers, with Mattie's husband passing and her remarrying a Younger.
My great-great grandparents were Lloyd Pinkney and Lucille and Merle, my grandmother
