Be very careful of what you find online about this Goodnight family. There are so many errors out there that I and several others have been trying to correct that it's turning us all gray.
Henry Robert Goodnight was the son of Henry Goodnight Jr. and Mary Huggins. He being born on the line between Lauderdale Co AL and Giles Co TN. I have seen most of Henry Jr's children list both TN or AL as a birthplace. I don't think they knew for certain which side of the line they lived on.
Henry Robert(aka Robert) Goodnight married Priscilla Rose, daughter of Jonathan Rose. You will find them in 1850 in Pulaski Co AR and then in 1860 in Van Buren Co AR. Robert later moves his family to Bell Co TX near the town of Holland. He and his wife are buried in the Holland Cemetery.
They are distant cousins of Charles Goodnight. Robert Goodnight's grandfather Henry Goodnight Sr. was the last son born to Michael Goodnight/Gutknect and Michael's first wife. Henry Sr is NOT!!! a son of Michael's second wife, Mary Landers/Landis.
