"Katsu Kaishu sought to make use of vassals outside of the domain and adopted a method whereby he selected the most 
talented among those who had surrendered at Hakodate and either sent them to serve under the Meiji government or 
dispatched them to other feudal domains. Examples of these men who were dispatched to other domains to provide 
instruction in education and military affairs are to be found in the well-known “Okashinin”, or “loaned persons” who 
went to work in the various domains, including Wakayama, Tsuyama, Nagoya and Fukui. These Okashinin took up their new 
roles by either one of two methods: they were either sent to domains directly by the Shizuoka domain upon their return 
home, or they had been sent to the various domains to serve their period of confinement and were subsequently employed 
locally."

豊富さが、藩士を、降伏人であるかどうかに関わりなく、御貸人として他藩や他地域に派遣することによって、人的
交流や「知識の共有化」を実現したことを明らかにした。

Nor is 貸人...
there's some evidence of the term (some more reuslts for お貸人 also) but it seems extremely obscure.
