Tracing William harrison (General)

On 11/01/1797 a William Harrison married Charlotte Mabbett, who was the daughter of Jane Colchester originating from Westbury Court. The marriage took place at Newnham Parish Coleford. At the time of the marriage Harrisons residence was shown as Penmark nr Cardiff and they subsequently moved to Merthyr where both later passed away, leaving several children. Enquiries show that William Harrison may in fact have been born in the Gloucester area. I have been unable to trace William Harrison back any further than the marriage in 1797. Can anyone help?
It is possible that his mother was named Emily. There is a family grave in the Merthyr area where an Emily Harrison is buried on 03/02/1826 aged 78. This would give her a birthdate approx 1748. I believe William to have been born 1773(possibly 1776)
Any help on either Harrison would be gratefully received. Thanks
