Kirill Khlebnikov was a Russian business agent who made several visits to Alta California. His "Travel Notes" from 1822 describe Khlebnikov's visit to Governor Sola in Monterey, who sent for "the Irish interpreter". (I think this means that their discussion was held in English.)
Who was the Irish interpreter?
Apparently John Mulligan, our Irishman from this question, was a man of many talents( and a couple of names).

Milligan acted as interpreter, as noted in the State papers
From The Irish Cultural Directory for Southern California - Page xvii
In March 1816, he acted as an interpreter when the captain of the Lydia was tried at Monterey on a charge of smuggling.

John Mulligan, or Milligan, the Irish weaver, may have arrived on the same occasion....an Irish resident, appears in 1 8 1 6 as interpreter for some English-speaking visitors.
