This timeline is an attempt to assemble a list of historical and natural occurrences that can be related to known ancestral data of the Ogle family, perhaps producing the conditions that was the impetus for an action.  Then I got carried away and added other data that interested me.

I am not confident of some of this data - but I present it as faithful as possible.  Credits are at bottom of first page.

One item below, for which I disagree is the year 1000:  States that Lief Ericksson was "blown off course" to arrive in America.  The sagas state that Lief Ericksson made a deliberate voyage seeking more places to settle.   Archeological evidence shows Viking settlements in Labrador and the small village of L'Anse aux Meadows on the northern tip of Newfoundland.  This may be the place of "grapes" that many deny could have been found here.  However in his time, vineyards were 300 miles farther north in England than even today.  A significant trade between the Viking settlements of Iceland, Greenland, and the American mainland and the Viking homeland flourished for some time.  But all contact with Europe stopped around 1550 when the weather became much colder and the North Atlantic could no longer be crossed.  At this moment the unsuspecting world was at the beginning of the "Little Ice age" which ran, with some warming periods,  until after 1850 which started our current warming cycle.  Europe was starving and had no time for settling North America.  What would it be like today if the "Little Ice age" had not occurred and all Viking settlements had prospered.   However, western European DNA has been identified in certain Amerindian Tribes of the Northeast.  Without contact with Europe the settlers must have merged with the local tribes.

Years A.D. -
Human Population 		Human Exploration and Activities
1900
(1.6 Billion)

Severe weather and climate events have increasing impact on society and environment as population grows from ~254 million to six billion people between the years 1000 and 2000.
 
1800
(813million)

Between 1849 and 1905, the most prolonged period of drought conditions in 300 years occurred in Arizona.
 
1700
(600m)

"Little Ice Age" chills much of Europe, with glaciers growing in the Alps threatening some mountain communities and shortening growing seasons throughout Europe. (Folland, 2001)
 
1600
(545m)

Slave trade, plantations and global commerce contribute to changes in land cover, influencing regional climate. Atmospheric CO2 levels are 6% below average Holocene level according to Crowley, 2000 .
1500
(425m)

Severe multi-decadal "mega-drought" hits American southwest, severely impacting native peoples who had only recently been invaded by Spanish conquistadors. "Lost Colony" Drought also effects settlement of Jamestown, VA, 1587-89.
1400
(350m)

Sailors from Europe and the Middle East learn to navigate the world's oceans using seasonal wind patterns later called "trade winds". The "Little Ice Age" begins to chill much of Europe.
 
1300
(360m)

Possibily linked to wetter, colder climates, Bubonic plague kills up to 20,000 people a day in Cairo. (See Stothers. 1999). Europe also hard hit. Empires thrive in Mali, Java and Uzbekistan. Minimum of solar activity during 14th Century.
1200
(360m)

1259 - Evidence of major volcanic event -- likely the largest during entire Holocene-- found in ice cores on both poles, (Crowley, 2000 ).
Great Drought (1276-1299) in American Southwest found in tree ring data impacted Ancient Pueblo and other native cultures. See Climate History.
1100
(301m)

Called "The Century of the Axe" by some historians because of the ambitious building efforts and clearing of woods for agriculture in Europe and elsewhere. Changes in land cover eventually contribute to changes in regional climate.

1000
(254m)

~1000- Leif Eriksson, returning to Viking settlements in Greenland from Europe, is blown off course and lands on the North American continent. Medieval Warm Period in Europe begins around 1000 and lasts until approximately 1350 AD.  Vineyards grew in Northern areas of England.  England produced some excellent wines in this period.  It therefore stands to reason that grapes would be growing also in parts of North America, probably along the same meridian as they did in England.

I have finally gotten back to this paragraph, it seems that 1950 is used only in relation to radio carbon dating.  While BC/AD is directly corresponding to BCE/CE.

Radiocarbon dating (sometimes simply known as carbon dating) is a radiometric dating method that uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbonaceous materials up to about 58,000 to 62,000 years.[1] Raw, i.e. uncalibrated, radiocarbon ages are usually reported in radiocarbon years "Before Present" (BP), "Present" being defined as 1950 CE. Such raw ages can be calibrated to give calendar dates. One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites. When plants fix atmospheric carbon dioxide (CO2) into organic material during photosynthesis they incorporate a quantity of 14C that approximately matches the level of this isotope in the atmosphere (a small difference occurs because of isotope fractionation, but this is corrected after laboratory analysis). After plants die or they are consumed by other organisms (for example, by humans or other animals) the 14C fraction of this organic material declines at a fixed exponential rate due to the radioactive decay of 14C. Comparing the remaining 14C fraction of a sample to that expected from atmospheric 14C allows the age of the sample to be estimated.

The technique of radiocarbon dating was developed by Willard Libby and his colleagues at the University of Chicago in 1949. Emilio Segrč asserted in his autobiography that Enrico Fermi suggested the concept to Libby in a seminar at Chicago that year. Libby estimated that the steady state radioactivity concentration of exchangeable carbon-14 would be about 14 disintegrations per minute (dpm) per gram. In 1960, he was awarded the Nobel Prize in chemistry for this work. He first demonstrated the accuracy of radiocarbon dating by accurately estimating the age of wood from an ancient Egyptian royal barge for which the age was known from historical documents.[2][3]

Posted from NOAA Paleo data 8/21/2009.  Notice the rise in temp beginning the end of 1000 AD, a dip in1250-1275, a up, down, up and down 1300-1425, a huge dip in 1425-1475, way low 1475-1650 w/slight ups, another bad dip 1650-1740, warming 1740-1820, continued warming since w/slight ups and down.

See how this fits with the time line showing volcanic activity.
