Hi Neville, I’m sure you’ve found out what you needed to know already, but I suspect we are related- I’m a direct descendent of Anna and Richard. I believe that the pair’s eldest son was called James Clarendon Ramsbottom Isherwood (born 1845), who married a Mary Jane McCormack and emigrated to New Zealand in 1866. James had a brother called Charles Edward- about him I know very little.
