For you in Canada, it will be IMPOSSIBLE to accord your friend a Kikuyu marriage. I also highly doubt it will be recognised by authorities. Kikuyu marriage as we know it is a process. It is not something you do in a day by 'accepting the bride/groom'. It may prolong even longer than a year before it is finalized.
If you are referring to the presence of Kikuyu artifacts, songs or even food, then you can get that in the wedding. But if you are referring to certain aspects of a Kikuyu wedding, then you cant have that.
For example, once a young Kikuyu man identified a potential bride, he could either elope with her (if they were in love), or organise for his parent to start the marriage process.. Thereafter the parents and wazees would visit the girl's homestead to report the elopement/interest in the girl. They would be given a particular day when they will formally come to report the crime/interest, and they will meet a batallion of wazees. They will then give 'njohi ya njurio' to literally book the girl from other marriages.
Then the dowry negotiations would start. In modern Kikuyuland, this takes a day. The relatives of the boy would give whatever they came with and promise to bring the rest later. During the final dowry payments, a goat and a sheep would be slaughtered and eaten. The shoulder blade may be cut then or on a subsequent visit.
The marriage ceremony ends with a ngurario ceremony. This is an extremely abbreviated version of a Kikuyu wedding. So, can you pick any aspect from the above?
However, if you want to serve food, mokimo should never miss. If you like alcohol, I doubt Canada will give you a license for muratina.
If you want dressings, they are no longer worn in Kenya and I doubt the bridegroom has ever seen any.
If you want songs, a Kikuyu wedding is accompanied by ululations and songs by women. I doubt you can get enough choreographed women for that..
But I know what you can definitely give them and they will be happy about it.....a honeymoon in Mount Kenya Safari lodge...1 week!
