Warfaa has to be much older then 200 years, I would say somewhere around 450 years. When I compared the Reer-warfaa lineage to the Reer-Diini of the Marexaan (the clan oo aad uu sii kala baxdey, ama laandheer ka ah Marexaan) Warfaa is 6 generations older than Diini, he is the same as Yusef Mataan, or his brother Hiiraabe Mataan, who was mentioned in futah al Habesha in mid 1500's.
BTW...is Boon-xersi the son of Cilmi-Warfaa?
Sade, i would be cautious at using such system to figure out the period of warfa or who ever, i dont thing warfa is 450s old, he is not 200years old either, going length wise, he is 300-350 at the most, i count 10 generations between me and warfa, dalal who is the grandson of warfa and hence i count 8 generations lived around year 1750s, also you have to look at the age of the father when he fathered the son, e.g. he might father his first son at 20 and his 21st son at 80 just like cheif Mohamoud Waal, so how do you take such descrepencies into acocunt? so if a man fathered his 1st son in his 20s and his 21st son in his 80s, the future lineage of each child is too much deferent and the numbers of the clans would be massively different just like hirsi dalal and wacays dalal, hirsi was 60 years older than his brother wacays and he used to carry wacays on his shoulders as a boy, hence by the time hirsi had his own granson wacays was born thus why hirsi dalal massively outnumbers wacays yet born from the same father. so just be careful at comparing two man in every generation like the merahan and ogaden in your example,
