Regarding John Peter Levesque's age, I don't believe he was as old as claimed. In the 1861 New Brunswick census, he states that he was 40 yrs old, making him born in 1821. In 1871, he states that he is 56 yrs old. He gained more than 16 yrs in age in just 10 yrs. By the 1900 Maine census, he states that he was born in May 1809, not 1803 as recorded by his death record.
Regarding the Searles Family history published by Robert Searles several years back, I have seen it and it is full of errors. Tom: yes, the death records are on ancestry.com. I will email you several from my email address firstname.lastname@example.org
