It's been a long since your post but if you are still active, I would appreciate contact. I too am researching Philip and Frances (Fanny) Eva from Helston, Cornwall. Philip died c1821 and Fanny remarried Stephen Cocking and had two more children. Her son Philip Eva Jr. married Jane Mathews and were enumerated with children on Channel Islands in 1851 before coming to Canada in 1854 where they are enumerated in Grey County Ontario 1861, more children born Canada. Fanny, her second husband and their daughter also came to Canada and settled Grey County. Dianne
