I believe that John Little was probably buried in Kent Parish, Carleton County (he died Dec. 1870) but I have never come across where he is buried. His wife, Mary, is found in the 1871 and 1881 census. No one seems to know what happened to her after that. Six or seven years later, it looks like the Levesques' and Littles' crossed over the border.
Having the 1890 USA census might have helped narrow down when Mary passed away. Having the 1851 Queens County census for NB would also help determine any other children John might have had - unfortunately neither one exist.
William Cooper Little would be my gggg grandfather - 2 of his sons being John Little and William Bell Little. I am a descendant of William Bell Little.
Transcribed from a couple land petitions in Queens County, NB:
From Land Petition dated August 7, 1820 for William and John Little
"They were born in Cumberland, England, where they always resided till' they arrived in this country last month. The
former is fifty five years of age, has a wife and seven children, four boys and three girls, the youngest thirteen. His son, John Little, is twenty six years old, is married and has three children."
NOTE: From Land Petition dated October 1822 for John Little
"A British subject of the ageo of thirty years, a married man with three children, females and migrated from Carlisle in England into this country in the year 1820."
Although I have never researched Peter Levesque, I have seen numerous postings in forums - seems he is quite the mystery too.
