Liz is seriously into genealogy and her researches take her back to parish records and wills etc written several hundreds of years ago - by hand, much on behalf of folk who could neither read nor write. Quite how she manages to decipher some of the writing is quite miraculous to my eyes, but you can see how easily the spelling of surnames was changed down the years.
The technical and historical knowledge of all things naval on the part of the collective forum members never ceases to astonish me!
