Another Go At Births and Ages

The following appeared in the newspaper Examiner, Charlottetown, PEI, in the 1 March 1880 edition [adjacent to the obituary of Catherine (Jenkins) Mutlow]
"A long lived family. - a notice of a death which appears in our column has induced us to make enquiries respecting a family remarkable for their great age to which its members have attained. Nicholas Jenkins and his wife emigrated to this Island from Germany about the year 1782 with three children. They settled first at Vernon River and removed after a short stay to Cherry Valley, from which place they came to Pownal, where they resided to the day of their death. After coming to the Island seven children were born to them, some of whom are still living. Nicholas Jenking [sic] the father died at 76. His wife 75, John Jenkins 90, George accidently killed 51, Susannah is still alive aged 100, William died at 92, Nicholas 90, Catherine 91, James still alive aged 88, Henry died at 81, Elizabeth 86 and Leanor 72."

This article, obviously taken from hearsay, appears to contain many errors. For instance: Nicholas Jenkins and his wife emigrated to this Island from Germany about the year 1787 with three children [John and Susanna (Henckel) Jenkins and Peter (Baum) Ballem].

Nicholas Jenkins the father, born 28 March 1755, died 15 July 1823, would have been aged 68 years 3 months 18 days.
Elizabeth his wife, birth date unknown, died 29 July 1823, was probably not 7 years older than Nicholas.
John Jenkins, birth date and place unknown, died 20 June 1866, if born about 1777 would have been 90.
Susannah, born 18 Dec 1785, died 14 May 1884 aged 98 years, would have been 94 in 1880, not 100.
George, birth date unknown, was accidently killed 30 Oct 1836, but if at age 51 would have been born about 1785 when the family was still living in Germany.
William, birth date in PEI unknown, if died at 92 earlier in 1880 would have been born about 1787, about the year of their arrival on the Island. Considered possible.
Nicholas, birth date in PEI unknown, died 1877, if died aged 90 would have been born about 1787. Considered possible.
Catherine, birth date in PEI unknown, died 10 Feb 1880, if died aged 91 would have been born about 1788. Considered possible.
Henry, birth date in PEI unknown, died about 1870, if died at 81 would have been born about 1789. Considered possible.
James, birth date in PEI unknown, died 24 Feb 1877, if aged 88 in 1880, would have been born about 1791. Considered possible.

Many of you have wondered before about the ages in that newspaper article. Has anybody thought of how it should have read? What are the actual birth dates of Nicholas' children? How old were they really at death? Can anyone help? If you don't wish to post a comment for everyone to see, perhaps you might email me on any of the postings at demacdonald@pei.sympatico.ca . Look forward to hearing from you.
