Tracing the Rhea Family Name
Rhea began as a Welsh family name. Elsdon Smith's dictionary of American family names explains it as “dweller near the rapids; dweller near the river Rea (river), in Wales”.
Heraldry and the Rhea name
Heraldry follows families, not surnames. A Rhea coat of arms, where one exists, belonged to a specific line.
