I have some family members from Cornwall, last name Tregonning, i have the surname spelt with a 'nn'. My ancesters are a Nicholas Tregonning who married a Martha Holman, they had an Ann Tregonning who married a Thomas Cocking, they were in Cornwall. Thats all the info i have on the Tregonnings. Thomas and Ann's grandson Nicholas came out to Australia and thats where i descend from. I don't know if its a line, but worth a try.
