The original family name was Rhodus in England.
We were told that anyone with the name Roadhouse would not normally be found in England as it is a North American name. Also, he said that anyone with the Roadhouse name is related in some form or manner.
In 1953 my grandparents, Ersel and Matie Roadhouse with other members of the family, had a professional tracer document the tree. The tracer followed the tree back to England. He said the Rhodus name was of German origin and possibly went back as far as the vikings.
It has since been further documented by other members of the Roadhouse family to add new names etc.
This family is well documented offline thanks to the work of many family members.
