Kalenjin are generally insular - we only truly happy amongst our people.
Kalenjin men or other girls will ostracize any Kalenjin woman who start dating outside...she becomes a pariah ... a dirty crap
So if she does...she is gone...forever. No kalenjin man will be interested in her forever..
But one who date within kalenjin...can be exchanged freely
Small percentage do marry - most of those marriages rarely last - except those married to Maasai.
The further a kipsigis woman will go is to marry a Nandi....and maybe other kalenjin subtribes (rare)
Then they marry Maasai, Gusii and Kikuyus.
It almost unheard of Kipsigis -Luo marriage - but I am told in border communities you will find them.
I know only Zakayo Cheruiyot married a Luo woman.
And of course Laboso married a Luo.
Luo-Kalenjin marriage are a rarity due to cut issues.
As for men - we can marry wherever - but still I see it rare and discouraged to marry outside.
So again - marry kalenjin subtribes, then maasai or gusii for us, and the few who dare kikuyus.
I have seen some marry somalis but apart from Zakayo and Laboso I dont know a Luo married in the whole of Kericho or Bomet.
Very very rare despite us being neighborhoods...few kipsigis women will accept to date Luo...and few Kipsigis men will do the same.
Kalenjin have saying Isach Kosachi gaa....shake well and make sure it spill at home --- something like that whatever you do make sure its stay at home.
Is it true your women do not marry other kabilas? I rarely see kipsigis or Nandi women marrying outside the tribe
