When I got quite interested in sirelines a dozen years or so ago I soon realised the vast majority of sirelines came by then from the Darley Arabian.
The Byerley Turk line was being kept going in GB by Lorenzaccio,who defeated a probably stale Nijinsky in the Champion Stakes. He came from a French line and sired Ahonoora who in turn had two quite successful sons in Indian Ridge and Inchinor,but I'm not clear that either of those had sons who stood at all successfully.
The Godolphin line was represented over here by Warning and his sons,quite a few of who went to stud but again I don't think any of them have established a line. Warning himself was a son of the Gns winner Known Fact a representative of a line long-established in the US previously unknown over here I think. It's possible that line is carrying on in the States through other sons of Known Fact's sire In Reality but I haven't noticed any recently.
Are we close to only having Darley sirelines ?

I've just remembered that the very good US horse Tiznow is from the In Reality line so there may be some hope there.
Inchinor sired Notnowcato but I wouldn't be confident he will found a line.

Here is some work I did a while back.

It shows the rise in some sire lines and the disappearance of others.
With an exercise like this you must pick a starting point.
I picked around 1920 and counted the number of offspring from that sire line by decade.
The data is from my database of about 382,000 horses.

You will see some sire lines e.g. Nearco (b 1935) increase every decade thanks to Northern Dancer (b 1961) and others.
The Peter Pan, Chaucer, Sunstar, The Tetrarch and other direct descent sire lines have disappeared.
It is rapidly becoming obvious that the only surviving sire lines are Northern Dancer (from Nearco) and Mr Prospector (from Sickle).

Northern Dancer and Mr prospector are descended from the Stockwell sire line.

Mr Prospector - Native Dancer - Polynesian - Unbreakable - Sickle - Phalaris - Polymelus - Cyllene - Bona Vista - Bend Or - Doncaster - Stockwell

In 2012 Dr Mim Bower published DNA evaluation that showed that Bend Or was really a stallion named Tadcaster.
That means that every pedigree with Northern Dancer is wrong.

The pedigree expert Harold Hampton (d. 1998) mentions in his book The First Scientific Principles of Thoroughbred Breeding Part 3 that the sire of Native Dancer (ancestor of Mr Prospector)
is probably not Polynesian as generally accepted but is more likely to be Challedon who stood at the same stud.

That means that 89.9% of the sires in my database born in the 2000s have incorrect pedigrees.

But the influence of a "sire line" is a bit of a fiction.
In a six generation pedigree the sire on the sire line in the 6th generation is 1/126 of the pedigree.
In a twelve generation pedigree the sire on the sire line in the 12th generation is 1/8190  of the pedigree.

Interesting stuff again kincsem.
I haven't got anything like your figures but it does look as though Northern Dancer and Mr Prospector will end up as the only sirelines ( the latter is nothing like as evident as ND in the British Isles,partly due to Coolmore,but seems to be developing an edge in the States. There IS still a bit more variety in the US. Some Nasrullah and Ribot lines still have some import. In addition I think Deep Impact who is having a very significant effect in some areas of the world is from a separate Nearco line.
I knew DNA studies had caused problems about early Stud Book entries but didn't realise something as relatively recent as Native Dancer was in doubt. Not only is he the founder of the Mr Prospector line but he was also Northern Dancer's damsire so that changes practically everything.
I take your point about the influence of one sire  but a lot of modern thoroughbreds would have Native Dancer in particular all over their pedigree.

The Harold Hampton book I mentioned (Part 3, publ 1997) was published posthumously.
“Harold recorded these chapters on audio tape and barely managed to have them transcribed before leaving us.  …. The Levin Breeders Forum (in New Zealand) undertook to oversee the production of Harold’s book”.

The only photo I’ve seen of Harold Hampton (1912-1993) is in the opening pages of the Part 3 book.
When I started looking at pedigrees in the early 1990s I bought the pedigree software package TesioPower and also some books from Jack Glangarry (NZ) who was selling TesioPower.
I bought among other publications two small booklets by Harold Hampton, The First Scientific Principles of Thoroughbred Breeding.
Part 1 was 40 pages, cost 10/6 NZ, published 1954.  Part 2 was 56 pages, originally published 1956 (my copy “Reprinted 1993 from an old poor copy by The New Zealand Turf Register”).

The question about Native Dancer’s sire is speculation by Harold Hampton.
“What we have to consider is Native Dancer’s racing ability, and that was of the highest class order, winning 21 races out of 22 ….
Now we come to the sire Polynesian’s part in this make up of Northern dancer, almost nothing at the 5th generation, very little at the 6th generation ….
But you have to go back to the 7th, 8th, 9th generation, and 10th to find any help there……
I do not regard it as strong enough, nor good enough to give Native Dancer such racing ability with his dam’s background accumulation of the Number 8 family of Beeswing.
Now while looking around to try to find out what could be wrong, looking up some old magazines of the “Blood Horse” published in America …..
that had the following adverts about a stallion that stood at the same stud as Polynesian; his name is Challedon.
By substituting Challedon in the place of Polynesian we get a whole host of what was beneficial to Native Dancer’s racing ability.

My comment: in the past it was very common to have a mare covered by a stallion and later by another stallion in the following month(s), with the result that parentage is often guesswork.

You might think pedigrees are mainly correct, but I have found many errors in the stud books everyone has on their shelves.
I wrote to the authorities and they accepted many and rejected some of my observations.
Some were real errors, some were printing errors.

Harold Hampton on page 177 of the Part 3 book mentions a New Zealand owner with a business exporting scrap metal to China.
One year he went to Japan on this business and left instructions with his wife and with his stud groom for the mating of his 120 mares and of the visting mares to his three stallions - which mare with which stallion.
A week after he went on the trip the stud groom, who had all the instructions, left, and his wife employed another stud groom.
The owner was delayed in Japan from September to November.
When he came back he did not know which mare had been mated with which stallion.
All he could do was make stud book returns based on his original list.

Harold Hampton said at another time he spoke to a visiting equine insurance agent.  (Part 3, pages 177,178, 179)
Hampton said he thought only about 97% of pedigrees were accurate, with about 3% wrong.
The insurance agent said “You can make that 11%.  Most of them don’t know the pedigrees of the horses they are dealing with.
I have to correct them all the time.  You can make your percentage 87% correct and the rest very doubtful.”

Is is possible to trace female lines by DNA.  Errors have been found, but stud books have not been/will not be corrected.
