eileenwilson, so good of you to go to so much trouble as to make a trip to search for more information. When I first joined this site 18 yrs ago I would bus downtown to peruse both archives for people. I know these searches aren't just around the corner.
How nice that you've found James & Harriet's first born'... "E.A." ...Elizabeth Ann Nosworthy Peard with her husbands forename on her memorial stone.
We have a lot of women with Scottish origins in the graveyards around my area. The women's names are prominent & most often show their maiden names as well. RESPECT!!!
How odd that under his father's Gravesite Details at Find A Grave site it mentions that "Charles Nosworthy owns all "12 graves" yet there are no others around. Come to think of it, where is Charles' stone or mention? No image on the site, either - Birth 09 May 1858 Death 12 Mar 1900
Just adding this because she ended up in Belleville as well
Not sure if related, but had this in my notes...

https://www.familysearch.org/tree/pedigree/landscape/KCS4-V28Adding having read the next reply this is not family but for those who may be searching, posting the son on 1861 census. Never know as her husband who died 1855 was also from Devon...and there's a gal with surname Martin, also b. Nfld. who may be with the household. Still could be distant rellies. 1820 marriage Marldon, Devon a wee bit of a distance ( as a teen I slowly walked 9 miles in about 5 hours) Marnaton & Marldon not that far from Ghudleigh, though...
