How far back can you go down your family tree before you start losing ancestors, and what is the percentage of your known ancestors going back generation by generation ? It's simple but also illuminating .
Working out the percentages from the data , most of my known ancestry (which is British and Irish) fizzles out long before the 10th generation. After that the percentage is so miniscule it becomes meaningless , so I stopped at the tenth.

This is related to individuals, not places, and it takes a bit of time to complete ; it includes the occasional female ancestor whose surname is unknown. I begin with the final generation where I can identify all of my ancestors by name , which in my case is the 5th .

great x3 grandparents = 100% (32/32)
great x4 grandparents = 67% (43/64)
great x5 grandparents = 29% (38/128)
great x6 grandparents = 10% (28/256)
great x7 grandparents = 3% (15/512)
great x8 grandparents = 0.6% (7/1024)

These few 10th generation known ancestors were born between 1635 and 1700 , and can be traced back to William the Conqueror, etc. It would be interesting to see how these results compare against others .

My recorded ancestors are all South-East English, mainly East Anglian. They are also mainly rural, poor, and working class. Only stated religions are Anglican, Methodist, Baptist, and Congregationalist flavours of Christian.
I start to lose from 3x great grandparents, as a result of an illegitimacy with unrecorded father. However, the percentages really tailor of with generation great x5 grandparent during the early 18th Century, as parish records start to disappear, fade, or give less information.

Much of my ancestry, particularly on my mother's side is incredibly localised in East Anglia, particularly in the east of Norfolk. I suspect that this is what gives my autosomal DNA test results, an atypically Continental flavour for a Brit. Subsequently there is some pedigree folding in the record further back, as I have a known 2nd cousin marriage, and 3rd cousin marriage.

I have no known heraldric or noble ancestry. My ancestors during the medieval were most likely the peasants of East Anglia and Southern England. Subsequently, my records do not stretch before parish records.

grandparents has 4 individuals. (100.00%)
great grandparents has 8 individuals. (100.00%)
great x2 grandparents has 16 individuals. (100.00%)
great x3 grandparents has 31 individuals. (96.88%)
great x4 grandparents has 57 individuals. (89.06%)
great x5 grandparents has 57 individuals. (44.53%)
great x6 grandparents has 46 individuals. (18.75%)
great x7 grandparents has 26 individuals. (5.47%)
great x8 grandparents has 6 individuals. (0.59%)
great x9 grandparents has 1 individual. (0.05%)
Total ancestors in generations 2 to 12 is 254. (6.30%)

Mine is
Greatx3 grandparents 32/32
great x4 grandparents 63/64
Great x5 grandparents 73/128
Great x6 grandparents 47/256 so up to here not too bad nearly 50% overall but it gets too depressing after that!

Only one line (illegitimate daughter of local gentry) can be traced back beyond parish records and others have done that.

~20/512, ~6/1024

I do not know the name system in GB.
It seems to me that the wife took the name of her husband, did not she?
This must in fact be complicated to find the mother's maiden name.
Fortunately, in France, mothers kept their birth surnames ...

36.6 % for great x9 grandparents ? I am guessing your ancestors haven't moved around much in the last few centuries ??? I would be happy for 3.6% , never mind 36.6% .

Unfortunately , English death certificates did not provide the maiden name of the deceased woman until relatively recently , and only ever gave the brides fathers name on the marriage certificate after 1837 . By contrast , from 1855 onwards , Scottish death certificates provided not only the maiden name but the names of BOTH of her parents .

France, like some other countries, has some pretty good records. But you're rather the Breton, aren't you? If you don't mind me asking do you have any serious ancestry from outside the north/northwestern corner of France?

None outside this area of northwestern France, since, at least, the 17th century.
It's even a small area in the northwest.

English parish records sometimes have the frustrating and really annoying feature of only listing the father on a child's baptism. After all the mother had no part in it!
I have occasionally found the mother from a marriage in the area but there are often about 3 potential candidates so brick wall time on that line.
Do other countries have the same annoying feature?

In the French registers, almost always the mother is indicated to the baptism.
Except for some old registers of XVIeme, or in the beginning of XVIIth century.

The parents of the bridegrooms are always indicated in the French registry office(civil status) (ie after 1793).
Very often, they are in the parish registers of the XVIIIth century, and less often before

Interesting in a way, when you think about it, coverture was a French concept introduced by the Normans apparently. And yet despite the time-gap British ideals still followed French in how the full entries weren't widely available to some areas until about the same time frame. For some. Others, of a different social class, had full entries earlier.

Some of the earlier Scottish registers do that, most frustratingly that includes Kilmonivaig which is probably the most vital register in the whole country. It doesn't have full parentage info for all entries until about 1820.

Unfortunately because of the slow system of getting records from Mauritius I have a big block missing only a few generations back on my mothers paternal line. Plus a few illegitimate lines as well. My best lines are from my Dorset and Friesland lines as they didn't really move around much all within a few miles radius for hundreds of years.

Great grandparents - 8/8 - 100%
2x Great Grandparents - 14/16 - 87.5%
3x Great Grandparents - 24/32 - 75%
4x Great Grandparents - 36/64 - 56.25%
5x Great Grandparents - 46/128 - 35.94%
6x Great Grandparents - 53/256 - 20.70%
7x Great Grandparents - 25/512 - 4.88%
8x Great Grandparents - 7/1024 - 0.68%
9x Great Grandparents - 1/2048 - 0.05%

The Icelanders don't need any more to search in registers!
The genealogy of all Icelanders is now at the disposal for the Icelanders!

http://icelandreview.com/stuff/views/2007/02/08/iceland-family-tree

More than 95 percent of all Icelanders born since 1703, when the first national census was taken, are registered into the database and half of all Icelanders who have lived on the island from the settlement in 874 and until 1703.

I think, we can never do it elsewhere!

Mine:
Great-grandparents = 8/8 (100%) "verified" by DNA 8/8 (100%)
great x2 grandparents = 16/16 (100%) "verified" by DNA 16/16 (100%)
great x3 grandparents = 32/32 (100%) "verified" by DNA 32/32 (100%)
great x4 grandparents = 64/64 (100%)
great x5 grandparents = 120/128 (93.75%)
great x6 grandparents = 220/256 (85.98%)

I have some lines where the surname is fairly rare, with a likely only a single immigrant ancestor of the surname. I have worked on tracing these lines, and in some cases have tentatively identified likely ancestors. However, this work also makes it much more difficult for me to accurately document the percentage complete per generation.

I have also started working on "verifying" my paper-trail ancestry with autosomal DNA testing. While I have done autosomal testing at the "Big 3" (23andMe, AncestryDNA, FTDNA) and have submitted my 23andMe results to Gedmatch, by and large only the AncestryDNA portal does an adequate job of linking DNA matches with the Gedcom folks submit. The downside of using AncestryDNA is that they have (to date) refused to release a Chromosome Browser. Without such a browser, we can never be certain common DNA segments actually came from common paper-trail ancestors. As such, I look for multiple DNA results to "verify" the line. I am still in the early process of doing this, so I haven't had time to compute how much of my paper-trail has been "verified" for my 4x great-grandparents and earlier generations.
