Saturday Night Genealogy Fun: Lifespans of Your Third Great-grandparents

Randy Seaver has a new challenge for this week's Saturday Night Genealogy Fun.  I'm glad he suggested an alternative for those of us who needed it.

Your mission, should you decide to accept it (cue the Mission:  Impossible! music) is:

(1) We each have 32 3rd-great-grandparents.  How did their birth and death years vary?  How long were their lifespans?  

(2) For this week, please list your 32 3rd-great-grandparents, their birth year,s their death years, and their lifespans in years.  You can do it in plain text, in a table or spreadsheet, or in a graph of some sort.

(3) Share your information about your 32 3rd-great-grandparents with us in a blog post of your own, in a comment to this blog post, or on Facebook or Google+.  Please leave a link to your information as a comment to this post.

Note:  Only list those you know about.  If you don't know many of them, do your 16 2nd great-grandparents.

I'm quite a bit shy of knowing the names of all of my 3rd-great-grandparents, much less their birth and death years.  I'm missing several of my 2nd-great-grandparents also, but proportionally not as many, so I'll list those as well as I can.  And I don't use Ahnentafel numbers.

Joel Armstrong, 1849–1921, 72 years
Sarah Ann Deacon Lippincott, 1860–about 1905, about 45

James Gauntt, 1831–1889, 68 years
Amelia Gibson, 1831–1908, 77 years

Frederick Cleworth Dunstan, 1840–1873, 33 years
Martha Winn, 1837–1884, 47 years

Gershon Itzhak Novitsky, about 1858–1948, 90 years
Dora Yelsky, about 1958–1936, 78 years

Victor Gordon, about 1866–1925, 59 years
Esther Leah Schneiderman, about 1871–1908, 37 years

Morris Brainin, about 1862–1930, 58 years
Rose Dorothy Jaffe, about 1869–1934, 65 years

I have reasonable information on only twelve of my sixteen great-great-grandparents.  I don't know the name of my paternal grandfather's father, so those great-great-grandparents are also unknown.  I know the names of my material grandfather's paternal grandparents, but I have no birth information and only very rough delineators for their deaths.  Even so, the birth years for half of my 2nd-great-grandparents (coincidentally, all of the Jewish ones) are very rough estimates.  On the other hand, the death years are estimates only for Joel Armstrong and Sarah Lippincott.

The average birth year for these ancestors is 1853, ranging from 1831 to 1871.  The average death year is 1913, ranging from 1873 to 1948.

The average lifespan is 61, covering a wide range of 33 to 90 (both of whom were men).  The average lifespan for men is 63, while the average for women is 58.
