Hi gwrmad

Yes I think you are right - I must look into this some time, but a big subject so not right now. This FH business is so time consuming, with so many fascinating byways. BTW someone sent me this morning a picture of the grave of bricklaying Esaias Pewtner which I hadn't looked for as my mother told me it had gone, so I'm a happy bunny!

Cheers

Joss
