Thank you Linda for the information sent.
However, there are still problems.
Mr Pinkwhistle had Timothy born in 1667 to John Chaleneur and Debra Brettargh. He also has Timothy as marrying a lady called Ann on 6 May 1703.
I now have no doubts that a Timothy Challinor, Yeoman, was the father of the John Challinor, who married Margaret Williams in 1717.
The problem is that I have now found a record of a Timothy Challinor baptised on 6 Dec 1666 in Huyton by Roby (very much Brettargh country) to a William Challinor. This William Challinor was baptised in Huyton by Roby on 29 Apr 1646.
There are at least two problems here. There is clearly at least one alternative father to the Timothy provided by Mr Pinkwhistle. The other problem is that we know John Challinor married Margaret Williams on 23 Apr 1717. If Mr Pinkwhistle is right and this John is the son of the Timothy Challinor, who married Ann in 1703, John would have aged 14 at best on his marriage to Margaret Williams.
Also , I don't think John would have received the Freedom of the city of Chester in 1721 at the tender age of 17 or 18. That doesn't make sense. As a barber (presumably a well respected one and possibly a wig maker as well), he would have had to have gone through his apprenticeship and trading independently before any such honour would be given.
Given the date of his marriage and the honour of Freeman, the earlier baptismal date of 1 Jan 1695 to father William would be much more likely., ie 22 when married, and 26/27, when he received the Freedom of the City and even that age would be good going to be honoured as a Freeman.
Again, we need Mr Pinkwhistle to confirm his sources.
