Dear Paul, That’s an interesting piece of irish history, so let’s take it up to a more modern era and assume that, even if the pedigree were contrived from strings of recorded people - fathers, sons, grandsons -, the generation times would not be altered within those groups. Is Somerled also mythical? Somerled is #20 in the pedigree, 23 generations before Frank McDonald. Using the same calculation, at 3 generations per century, Somerled would have been born 767 years before Frank McDonald, in 1159. The article indicates that Somerled died in 1164. So, going back 23 generations (767 years), the estimated year of his birth, based on 3 generations/century, is off by 28 years.
