Hi Michelle ......
Hope you get sorted with this one !!
I have looked on 1837online for you , and searched for his death , in 1847 .....there are no William Kitchings' registered at all in that year......
If there was an inquest , I would imagine a death certificate would be issued after the coroners inquest . If it was indeed a murder , or suspicious death , and a trial was held , this may have taken some time.....I will have another look in 1848.
Have you thought of contacting Guisborough library ? There may be some sort of records about it , and research staff are usually very helpful........
Kind Regards
