The Chronicles of Thelwall, Co. Chester
    Published 1846, J. B. Nichols
The Pickering  family, who were next in possession of the manor of Thelwall were of a very  ancient descent in the county of Chester, and appear to have been, from time  immemorial, landed proprietors in the palatinate. In the reign of Queen  Elizabeth they were settled at Walford,  in the parish of Runcorn, which had long been the seat of their ancestors,  and the names of members of the family for successive generations will be found  in the early registers at Daresbury. 
In Lysons'  Cheshire, p. 400, the author observes, " The Pickerings were of Walford,  in Mobberley, in the reign of Queen Elizabeth." From what source this  information could be derived, I am certainly at a loss to know, the fact being,  as I now find, that there is no such  locality as Walford in Mobberley. At the time, however, when my attention  was first directed to the history of the manor of Thelwall and its successive  lords, I was ignorant of this, and relying on the authority of Mr. Lyson’s,  diligently searched through, (over and over again,) the registers of the parish  of Mobberley, but without finding any mention of the Pickering family, at which  I was naturally much surprised. 

The Pickering Arms in the early 1900s.
It was only on an  accidental search into the registers at Daresbury that I detected the error the author had made, the members of the Pickering  family being regularly entered there, by their description " de  Walford," (which was the name of an estate within the chapelry of  Daresbury) and corresponding with the pedigree at the Heralds' College. The  mystery thus unraveled certainly cost me much fruitless labor and research, and  it is one of those instances which not unfrequently occur proving how jealously  scrupulous the historian (above all other writers) should be, lest he allow  himself to arrive too hastily at a conclusion, and without evidence sufficient  to warrant it. I can only account for the error into which Mr. Lysons has  fallen, from the fact that there is a township of Warford adjoining to  Mobberley, and probably he thought that "Walford," mentioned in the  pedigree at the time of the Heralds' visitation, was entered by mistake for  "Warford."
