Thanks Shaun - you have just solved a family mystery !!!

My cousin has a very small picture with a note attached to it. It says,
Uncle Thomas Wood Thompson. Finished his education as a Dr and worked the hospitals in Dublin when his uncle Vaughan Thompson, a navy surgeon was appointed inspector of hospitals. Uncle Thomas died in England in 1833 at the age of 21.
The uncle Vaughan appears to be John Vaughan Thompson the botanist and zoolologist and now I can confirm my suspicion that Thomas Woods Thompson was the brother of my ancestor. Thanks !

Also thanks Ken. I'm working on the BMDs but as for wills I have only found one for a Joseph in Berwick who died in 1784. He only has one son John and grandsons Joseph, James and Vaughan. The Vaughan is the above Vaughan (I think) and Joseph is likely the one fathering Thomas Woods and my ancestor John Hall.
