Thank you for your replies.
I simply wondered to what extent the modern and antique definitions coincided.
So far I think the connection must come from the family of Gabriel Wettenhall's mother, Margery Maisterson, daughter of a significant gentry family of Nantwich. I have been able to establish, from wills and Herald's Visitations, that Richard's wife Margaret Walthall was Gabriel's first cousin, daughter of Margaret Maisterson and Roger Walthall, but I can't seem to place William and Alexander. They can't be Richard's children. I had wondered whether they might be his brothers, or even nephews, but there is no proof. Richard's father, Henry, married a Mary Hassall, but her father is stated as Henry Hassell of Hankelow, not the Richard Hassall of Nantwich who married another of the Maisteron sisters (Ann). Could an error have crept into the pedigrees, confusing one of the many Richards for a Henry? In one of the visitations of Somerset I came across a case where a man's residence, Huish, was thought to be his Christian name, Hugh, instead of his actual name as confirmed by PRs and PCC will. A few leads remain for me to follow up, then I'll post on the Cheshire forum, as I'm a Somerset man and am not that familiar with Cheshire records.
