She was certainly born in Moncton since her family is listed there in the 1951 and 1961 censuses flanking her birth.
Birthdate listed as Apr 21 in the 1901 census and the birth year looks like 1857 (correct) written on top of 1860, smudged. It lists her age as 40 in 1901 which is wrong and likely was based on the mistaken initial entry for the year of birth.5
The 1891 Census said she was 32 which would make her year of birth 1859 but the Jones bible said 185718 and the 1861 Census said she was 4 years old.32 Her birthday of Apr 22 is confirmed in both the Jones bible and in Frances Burt’s “Longfellow Birthday Book”1
Educated in a Convent after her mother died and eloped with a sea captain according to Kathleen Givan although this may be over romanticized as there is the newspaper announcement of their wedding occuring in the home of the bride’s father.4
She died of a cerebral hemorrhage while visiting daughter in Malden, MA. Cemetery records say Medford (Malden and Medford are side by side and she had a daughter in each area)

from Feb, 1927 Moncton Times:
