John Goudy was my great-great grandfather too (directly through the paternal line). If you go to http://www.1901census.nationalarchives.gov.uk/main.asp?wci=welcomehttp://www.1901census.nationalarchives.gov.uk/main.asp?wci=welcome and type in John Goudy you will find the family, or I can send you the details if you prefer. I expect you have all this information now as your posting was some years ago.
My father is David Sanderson Walton (born DS Goudy, Walton is his step-father’s name), my grandfather was Hugh Percival Goudy, my great-grandfather was John/Jack Goudy (b 1893) and my great-great grandfather was the John Goudy (b 1860/1) whom you posted about.
Are you related to Eleanor Howarth (née Goudy)? She was my great-grandfather’s sister and was there at his death in 1951. I am keen to find any Goudy/Howarth relatives who might be able to tell my father and I anything about his father, Hugh Percival Goudy, who died in sad circumstances in 1941, 2 days before my father was born. Unfortunately there was no further contact between the Goudys and my grandmother (Catherine Goudy, née Sanderson).
