I can add more about Generation 6, 7, and 8 decending from Otto Willis Maltby and Cathern R. Tandy (d. 1997). Their children are Thomas Edward Maltby, Willa Hundley , Mary Giffhorn, Timothy James Maltby, and Patty Waldon. Thomas Edward is my father. He had 1 son with a previous wife: Thomas Edward Jr (deceased). His other children are Melanie Ann Maltby and Meghan Ruth Maltby. (Mother: Beth McLaughlin) I, Meghan Ruth, am married to Daniel Adam Riegerix. We have 1 daughter: Willow Jane. Melanie is marrying Garrett Long on Oct. 2.
Aunt Willa has several kids, but they live in KY, so I don't really know them. I just know Paula Lundsford is her daughter.
Aunt Mary's children are: Tina Cathcart, Debbie Hager (married to Gene), and Diane Hause (Married to Jon)
Uncle Timmy and Aunt Carolyn's children are: Tammy Avery (married to Matt), Nicole Landsverk (Married to Brandon), and Timothy James Jr (also married but I don't know her name).
Aunt Patty's children are: Ashley, Candice, and Jared. (all 3 have different last names. I don't know them well.)
Most of my cousins do have children, but unfortunately I don't know all their names.
