33 generation tree

[Finley 1]

I used to use PAF file that can print out trees...

its a heck of a lot of work adding 33 gens to any ged to enable the production of a tree.

xinI have a twig ... if you stick it in the ground it may root, but then it may not.  Sometimes I look at the trees and see the tangled web of branches and wonder.
Then I sit and concentrate on that one delicate branch and follow it all the way to the top, but then it is so delicate that it often snaps.. breaks or twists..

"A tree descending through mother’s male lineage stating in circa 1450 is 13 generations to my grandchildren"

That gives a generation time of about 43 years - not impossible but certainly extremely long.

Many years ago, when I took a population statistics course, average human generation time was considered to be 28.5 years.  That means, using definition #2 [difference in age between parent and offspring], that the average child is born when its mother is 28.5 years old.

My tree goes back to 1540/1550 - 16 generations on paternal line; 18 generations on maternal line.

As a reference point, the Vikings ruled the Isle of Man from 1079 (Godred Crovan) until 1265 (Magnus Olafsson). So, Vikings aren't very far back

Circa 1948 and I was a youngster in a classroom of 39 pupils learning about graphs and averages.  We were told there were three generations per century.  The lesson regarding averages required us each to give the age of our mothers when they married and I thought about lying about my mother's age because she was absolutely ancient compared to the other ages being quoted.  My mother married the month after her 20th birthday, whereas most of my classmates mothers married when they were eighteen years old.

Rena, that reminds me of when I was about 8, and had a conversation with my little friends about how old our mums were.   My mum was 33 when she had me, so she had by then turned 40. My friends' mums had had them whilst aged 20/21 ish, so were still in their 20's!   
I felt as if my mum was absolutely ancient.

Looking at one of my charts a 33 gen. tree would be roughly 6' x 18' long.
Laterally mine stops C.1400 & then goes up.
Depending on when you get onto the greasy pole of Nobility you might be looking at a tree 30' long.

You would need to live in a Mansion to hang it on the wall

I suggest your calculations are out somewhat.
My full tree held on 3 maximum size 200 inch pdf files if printed would be 50 feet wide not sure of the height, but that is not really a concern as it is the width for the generations to fit side by side that is the controlling factor.
I have an outbuilding with three walls with no doors or windows in them that could display the tree if I ever got it printed but I don't really think it justifies the cost when I can display it on my computer monitor.

The intriguing mathematical point is that (as has been pointed out) going back 10 generations leads to 1024 ancestors; another ten should lead to just over a million.  Using the suggested average period of 28.5 years per generation, that is 570 years, or around 1450 AD.  The population of the British Isles then was only a few million.  So even allowing for possible ancestors from all over Europe, almost all of them could be in anyone's tree in 1300 or so.  So we are all related ! 

Of course in reality that means the tree contains a lot of overlaps, so laying it out will be rather difficult ....
