Herbert

In particular Herbert, Earl of Pembroke.
Herbert is listed as "Our common ancestors":

My wife has a spectacular descent from Henry Herbert, 10th Earl of Pembroke, so that line is done in great detail.
My descent from Herbert is quite different, and is uncertain. I descend through Blennerhassett from Mary Herbert. She is believed to be of the family that descends from the brother of the 1st Earl of Pembroke (of the first creation). But Mary's parentage is uncertain.

This family does not descend from the Norman FitzHerbert family

Genealogies have existed for centuries claiming to show the Herbert male line above Adam (born est c.1255), and in particular claiming descent from the Norman FitzHerbert family.
While that family did exist, [Clark, 1886] and others argue that these Herberts do not descend from them, and these genealogies were faked at an early period to show a Norman origin for the Earls of Pembroke.
Darrell Wolcott agrees, and argues that the true origin of Herbert is native Welsh.

We begin as follows.
The surname "Herbert" was not established until the children of Sir William ap Thomas.
