Don Mack Dickinson was the sixth of twelve children born to Charles Wesley Thomas Dickinson and Josephine W. McManus, both of whom were from pioneer Texas families. Charles Dickinson was the tenth of ten children who grew to adulthood born to Dr. Samuel Burling Dickinson and Caroline Elizabeth Kinnison. An eleventh child, a baby boy, died as an infant.

Samuel Burling Dickinson was directly descended from four passengers who were aboard the Mayflower on her maiden voyage to America that arrived in Nov 1620 (John Howland, Elizabeth Tilley and Elizabeth's parents); thus Don Mack Dickinson was descended from them, too.

SBD is a qualifying ancestor for membership in the General Society of Mayflower Descendants, the John Howland Society, the Sons of the Republic of Texas, the Daughters of the Republic of Texas, and Texas First Families.

Don Mack Dickinson is believed to have been named for his mother's next younger sibling, her brother, Don Gerome McManus. Don Mack's given middle name was shown in one transcription of an old family Bible as McManus and in another transcription as Mack.
