Going over my files and notes, I do not think there was a Margaret Hartin daughter of Joseph and Catherine. There is a Margaret on 1861 Camden East census but she is indicated to be married and so I think she was Margaret Sweet wife of George Hartin, son of Joseph & Catherine. A note at page bottom says George and Margaret married in 1860.

Another reason I thought there was a Margaret Hartin is because Joseph shows up on LDS site in 1881 census this way:

Household:

Name Marital Status Gender Ethnic Origin Age Birthplace Occupation Religion

Joseph HARTIN M Male Irish 80 USA Lab
John H. WILSON M Male Scottish 38 Ontario Farmer Presbyterian
Margret WILSON M Female English 38 Ontario Church of England
William WILSON Male Scottish 12 Ontario School Presbyterian
Lora WILSON Female Scottish 10 Ontario School Presbyterian
James WILSON Male Scottish 5 Ontario Presbyterian
Laurance WILSON Male Scottish 3 Scotland Presbyterian

HOWEVER, after checking this Wilson family, Margaret wife of John H. Wilson was Margaret Ann PRICE, not Hartin. And I do think that the LDS folks cut off Joseph in the census from the household he was supposed to be in, (I have seen this happen now a few times) namely:

Household:

Name Marital Status Gender Ethnic Origin Age Birthplace Occupation Religion

Jehial HARTIN M Male Irish 52 Ontario Lab C. Methodist
Elsa HARTIN M Female Irish 50 Ontario C. Methodist
John HARTIN Male Irish 16 Ontario School C. Methodist

Sorry for any confusion in this matter. I therefore only have names of five sons for Joseph Hartin and Catherine Prosser, (William, Daniel, Jehiel, George and Nelson) .....there could be more, there was a John Hartin living at Camden east in 1861 as well, and there could be married daughters. In fact that John Hartin on 1861 Camden census, born about 1820, wife Mary Ann Teskey born Ireland about 1823, had a son named John PROSSER Hartin born about 1848, what do you want to bet this family also related....

Would like to hear from anyone researching these families.
