Wow, what a site - you must have put in so much effort!

I have finally found my fabled Cornish connection after almost a year of searching and am descended from Margaret Vingoe (1812) who married Richard Walls in 1836 (through their daughter, Grace).
One question if I may - how did you determine which of the 2 Margaret Vingoe's was 'Peggy'. From the census, I could not work out her real age and therefore could not determine whether she was the Margaret born in 1812 or in 1820.

Many thanks....
