Q:

Where was Timothy Kelly born (married in London, died in Herefordshire)?

My ancestor Timothy Kelly, died in Weobley, Herefordshire, in 1839, and was born around 1774, according to the age given on his death certificate.
Supposedly, his son told descendants that his father was from Ireland, but we've been unable to find him there.
There is a Timothy Kelly born in Clerkenwell at around the right time, but there's just not enough evidence yet.
I'm wondering what resources I should check next to try to figure out where Timothy was born and who his parents were.
Most of the research has been done by my grandmother. Personally, I have done basic searches on Ancestry and FamilySearch, but that's all.
I have uploaded all of the images I have to his WeRelate page (linked above) and to his family page. I have marriage records for his first marriage, but they don't mention his parents. There is a record for his second marriage (Film #1,041,603), but I don't have the transcription, or an image. That was research done by my grandmother, so I'm sure it doesn't list parents' names either, or she would have noted it.
This marriage occurred at St Peter, Hereford, Herefordshire, but I can't find the St. Peter, Herefordshire Parish records online for this time period.

A:

Does the previous research include source citations?  When was it done?  What resources were available then?  Were original rescords consulted or indexes.  Bear in mind that previous work may not be correct, so it is a good idea to verify it.
Whilst online records are very accessible and can yield results quickly, only a tiny proportion of records are online.  The original parish registers should be in the county record office.
The informant on the death certificate was the attending doctor.  He may not have accurately know the age, so try a range of dates in your searches.
