I have been in communication with a John Richardson from New Zealand and he has done a lot of research on the Townsend family. There is a lot of confusion about John Townsend 1753 who married Sarah. We can say that they were living in Longhope but in 1790 John and Sarah and their 4 children upped sticks and moved to Brockhampton Herefordshire where they produced another 4 sons and two daughters.
I have visited the old church in Brockhampton and saw the graves of John and Sarah and various of their children.
There is quite a lot of information that John found out about the children of John and Sarah. These children were Celea 1783 Longhope, Elizabeth 1786 Longhope James 1787 Longhope who married Mary Ann possibly Hope who was born in Bristol 1787. Thomas 1787 Longhope. John 1791, Sarah 1793, Charles 1795, Richard 1797, William 1799 and Lettice 1801 were all born in Brockhampton.
Best wishes
