Closing Remarks .... or so I thought....
I discovered two relevant family trees that helped me go back further in time than ever before. Back to John Burnard of Laneast, born in 167o - no less! One by Roger Sando and the other by the Wotton family - a big thanks to them! Perhaps I can return the favour with some of these pictures. By the way, the connection to the Wotton family dates back to 1826, when Eliza Burnard (a sister of Mary's dad) married Hampden Wotton of Plymouth.
But, as with all good research - it raised more questions than answers. I came across at least two other branches of the Burnard Family: One that left for Adelaide, Australia in 1839 headed by Robert Burnard, a portrait painter. Could Robert the photographer have been inspired by Robert the painter? Certainly places like Laneast, Altarnun, Lewannick and Launceton are very close to each other. I also spot a certain family resemblance, so my bet is that they are related. Another branch of Burnards in the USA lived in Ohio . Were all three lines related, perhaps ?? Are there more in Canada and South Africa, as the Burnard blog on this site suggests? Some other time ...
For now, I will wait to see what other material turns up and post it as it comes along. The next mission will be to find out what happened to Robert in the USA - hopefully in time to tell Gerda.
