I just found a website that has a section entitled 43 Generations: from Colla Uais to Frank Everett McDonald, Jr. (#133546). Colla Uais was one of the three Collas, born in Ireland in the 4th century. Frank McDonald was born in 1926 in Virginia, USA. http://www.peterspioneers.com/colla.htm#mcdonald Previously, I posted my 47 generation icelandic-Irish pedigree between my birth in 1937 and Niall's birth. At 3 generations per century, the number that my pedigree indicated, Niall would have been born 1567 years before me, in 370 CE, in the 4th century when he is widely believed to have been born. However, if the calculation were done with 25 generations per century, it would have placed Niall¹s birth 1175 years before mine, in 762 CE, in the 8th century. Using the same calculation for Frank McDonald, at 3 generations per century, Colla Uais would have been born 1433 years before Frank McDonald, in 492 CE, in the 5th century. However, if the calculation were done with 25 generations per century, it would have placed Colla Uais¹ birth 1175 years before Frank McDonald, in 851 CE, in the 9th century. So, we have two independent pedigrees which indicate that the generation time M222 people are interested in was a lot closer to 3 generations per century than to 4 generations per century. Incidentally, I could show that 3 generations per century held up over different parts of my pedigree - in Iceland , in the USA and Canada and in ancient Ireland. David

Hi David, Here's some other independent pedigrees with the same results. I have a paper genealogy trail back to Niall also that consists of 49 generations, and I was born the year before you (1936) or 1566 years after Niall. Dividing this out gives 32 years per generation or about 3 generations per century. This line goes thru Niall's son Eoghan. Another line I have goes through son Connal Cremthann and consists of 51 generations. This line yields 30.7 years per generation. Dividing your results out gives 33.3 years per generation. So there you have it; 3 lines with 3 different answers but all much closer to 3 generations per century than 4. I thought perhaps in more recent times the years per generation would be lower, but looking at my last 10 generations (all in the US) I get 327 years or 32.7 years per generation; no difference. Can anyone produce numbers that support 25 years per generation?

The tree Colla's are regarded as Mythical, leaving aside that there supposed floruit is 4th/5th centuries. The genealogy has been fabricated to give the Oirialla (Airghialla) a lineage that connected into the Dál Cuind (Dál Cuinn aka: Connachta and Uí Néill) -Paul (DF41+) On Sat, May 17, 2014 at 10:46 PM, David Maclennan < david.maclennan@utoronto.ca> wrote: > I just found a website that has a section entitled 43 Generations: from > Colla Uais to Frank Everett McDonald, Jr. (#133546).

I have map out a number of pedigrees and spaced them out with the year of their death. These pedigrees support 3 generations per century. On the other hand using the mutation rate for 25 markers and assuming dynastic surnames trace back to a 10th century originator I find support for 4 generations per century. I wonder if the mutation rate is off?
