William Chambers came to County Mayo, Ireland in the early 1600's. He and his family resided at Kilboyne House. He was knighted as was his son, Robert. The cost of arms featured a chevron with three cinquefoils. In Burke's Armoury the family came from Hertfordshire.
There is a strong possibility that the male line descended from Norwegian Vikings.
Has any male Chambers in Hertfordshire taken the yDNA test?
