Wow, how's that for service!  
The reason all this family history started is because i own a family bible and the first entry in it is by Samuel Hignett, born January 19, 1746/47 in Thornton le Moors.  He died in January 1817.
I live in Somerset, so I am trying to use the internet as much as I can, and came across this forum only this afternoon. 
I have no records at all any earlier than 1746/47, but if you can find anything, with the spelling Hignett, and for now ignore the others, does that narrow your search down, to at least a manageable number?
For this reason I am unable to give you any Christian names, but a bit more information about "my Samuel".
He married Hannah Manifold on 5 October 1772 by licence.  Thomas Hewson was the vicar and the witnesses were Joseph Hignett and Peter Manifold.  We might assume (dangerous, I know!) that Joseph might have been his brother?
So for a start, maybe try Samuel, Joseph or William!
Thanks again,
