The roots of the Anglo-Saxon surname Hyatt come from when the family resided in the village of Ayett in the county of Hertfordshire, England. The surname Hyatt can be translated as at the high-gate, a gate that led into a protected enclosure.
The word "gate" may not refer to "gates" at all, but to "geats" or roads. So, this surname may also be interpreted as one in residence at the high road.
