Zachary TAylor Dyer was born circa 1880 in Giles Co., TN. and migrated to Dallas, TX. sometime around 1900 or so. She was the son of Zachary Taylor Dyer, Sr. Zachary, Jr. had siblings: Anna, Mary Frances, Sadie, William, Thomas.
He could have married Plassye Belle Bearden, as I found on the Dallas Co., TX website under births where a Zackery Taylor Dyer and Plassye Belle Bearden Dyer had a daughter born Oct. 30, 1929 in Dallas, TX. named Rita Marie Dyer.
