Life Span of People

As we try to trace back our progenitors, we have to try and imagine what life was like in the past.  This is important as it is related to the life span of our ancestors.  Researching the internet, we came across this table -

Life expectancy - Timeline for humans

Humans by Era, Average Lifespan (in years)

• Neanderthal, 20
• Neolithic, 20
• Classical Greece, 28
• Classical Rome, 28
• Medieval England, 33
• 1800's End of 19th Century, 37
• 1900's Early 20th Century, 50
• 1940's Circa 1940, 65
• Current (in the West), 77-81

The earliest information we have of our Neri forefathers goes as far back as the 1800's.  As of now, we have NO record or reference that would connect the brother's Leon Neri and Salvador Neri, the other Neri's at that time, namely Juan and Lino Neri directly to the Sampurna.  We only have anecdotal information of relatives from the Lanao area coming to visit and relating the ancestry and connection of the Sampurna's and the Neri's.  We take it on faith that the stories of our lolos and lolas have basis in fact.

So what is the reason for showing the lifespan of people through the centuries?  According to Amadeo Neri, the first name change from Sampurna to Neri was in 1779 with the Christianization of the Sampurna family in Kagay-haan by a Recolletos friar by the name of Rev. Pedro de Santa Barbara.  The earliest record or mention of the Neri's seems to have occurred in th 1800's, which is only a period of 31 years.  This gap is what we need to fill to connect the Neri's to the Sampurna.  This is equivalent to only one generation if lifespans at that time averages 37 years.

So short a period yet so difficult to connect.
