Ancestors of Theodore Harvey

For those not familiar with Sosa Stradonitz, it is an improvement on the Biblical patrilinear only genealogical system. Sosa, the earlier inventor, was actually a Franciscan arguing about genealogies of Our Lord in Matthew and Luke : while several between King David and Our Lord are same generation, they are different "ancestry numbers". You don't have ONE grandfather, you have TWO, and unless you are grandchild of Adam, or product of incest, they are different people. This system has "the person concerned" as number 1, any father of any person n as 2*n, thus father of person concerned 2, paternal grandfather 4, any mother of any person n as 2*n+1, thus mother of person concerned as 3, maternal grandmother as 7. This means, parents are 2 and 3, grandparents 4 to 7, great grandparents 8 to 15 ...
But here we get to the generations which were certainly born before industrial revolution started improving things, though not all before it started deteriorating things:
- Great-Great-Great-Great-Grandparents
70. Charles Wright (Cornwall)
71. Priscilla N
72. Isaac Westlake (1779, New York, NY – 1872)
73. Gee N
74. N Sears
80. Shadrack Felton (1804 – 1865)
81. Susan Savage (1805 - ?)
82. John Clark(e)
83. Elizabeth Matthews
84. Peter Parker [no, not this one, Marvel fans!] (1775/84 - c. 1828, Gates Co., NC)
m. 6.19.1805
85. Elizabeth "Betsy" Brown (1780/4 – 1847)
- Great-Great-Great-Great-Great-Grandparents
148. Isaac Sears (1730 – 1786)
160. Noah Felton (1764-1814)
161. Jane Riddick (1768-1834)
168. James Parker (c. 1765 – 1805)
m. c. 1782 [when both were 17]
169. Judith Copeland (c. 1765 – 1823)
170. James Brown (c. 1760-1797)
171. Christian Parker (c. 1765-1799)
- Great-Great-Great-Great-Great-Great-Grandparents
320. Richard Felton (1720 - 1776)
321. Ann Harrell (1735 - 1792)
336. Josiah Parker (c. 1735 - 1789)
- Great-Great-Great-Great-Great-Great-Great-Grandparents
640. Richard Felton (1690 – 1764)
642. Richard Harrell (1710-1762)
643. Margaret N (? - 1735)
Obviously, among the Great-Great-Great-Great-Grandparents, 64 to 127, many are missing. Even more from the previous generations. But those who are there were not included in the known part because they had exceptionally long lifepans.
And, this will involve some with known lifespans, though in two cases there are two alternatives about birth years. This will leave median unaffacted, but will differ upper and lower quartiles a bit. Here we count the known lifespans:
(1779, New York, NY – 1872) 93
(1804 – 1865) 61
(1775/84 - c. 1828, Gates Co., NC) 44 / 53
(1780/4 – 1847) 63 / 67
(1730 – 1786) 56
(1764-1814) 50
(1768-1834) 66
(c. 1765 – 1805) 40
(c. 1765 – 1823) 58
(c. 1760-1797) 37
(c. 1765-1799) 34
(1720 - 1776) 56
(1735 - 1792) 57
(c. 1735 - 1789) 54
(1690 – 1764) 74
(1710-1762) 52
16/24 are known with lifespans. And how do they line up for medians and such? Note, since there are two persons with two alternative lifespans, it would be possible to make 4 different line ups. With three, 8 different lineups. With 4, 16 different lineups. In such cases I only do one with each at the lower count and one with each at the higher count, making these the outer limit cases.
Lower count:
34 37 40 44 50 52 54 56=56 57 58 61 63 66 74 93
01 02 03 04 05 06 07 08=09 10 11 12 13 14 15 16
Higher Count:
34 37 40 50 52 53 54 56=56 57 58 61 66 67 74 93
01 02 03 04 05 06 07 08=09 10 11 12 13 14 15 16
So, these guys, obviously not involving those who died too young to marry, died around 56. Either 50 % were dying between 50 and 61 (lower count) or 50 % were dying between 52 and 61 (higher count).
As Theodore is a fan of Monarchy - and so am I with historic at least monarchy - it fairly well matches ancestry of Louis XVI or of Marie Antoinette.
