The IGI gives the following entry:
Charles HENDREN married Maria MAYFIELD, St Phillips, Birmingham, Warwick. (Batch M04179-1).
There appears to be no other record of any kind (not that I've found!) relating to a 'Charles Hendren'.
It seems more likely that his name was George Hendren, based on the baptism records of what appear to be his two children (he - whether Charles or George - died before the first census, so I have no record of him with them).
If anyone has access to the records of St Phillips, could they check the entry, as I suspect the IGI may be in error.
Maria Mayfield is alternatively called Marianna or Maria Anna. She would have been a minor, as appears to have been born on 10 Aug 1801.
With thanks for any assistance
