miss Parr 6.7.1794 in Norwich (coded in GD website as Sarah Parr).
I tried to find any other Miss Parr in Norwich; Samuel Parr had a cousin the Rev Robert Parr of Norwich (d.1812) but in his and his father's wills there is no sign of his having had any sisters or daughters, so Sarah Parr on a visit to her cousins seems a reasonable guess
